David de Gea, Joe Hart and goalkeepers whose careers went downhill fast

The Manchester United No 1 messed up - again - against Chelsea in the FA Cup semi-final

Manchester United's David de Gea has made a string of high profile errors in the past two seasons having previously been regarded as one of, if not the best keeper in the world. His most recent clangers came in the FA Cup semi-final against Chelsea. Nothing seems to be sticking to his gloves these days. Reuters

Joe Hart is the most obvious example in recent years of a keeper whose career has suddenly faltered. From England and Manchester City No 1 to being unable to get a game and subsequently released at Burnley. Quite why it has happened is somewhat of a mystery. He was England's best keeper since David Seaman, but like de Gea the errors became more frequent. Getty Images

Victor Valdes' trophy cabinet was brimming after more than 500 appearances for Barcelona. Then came two games in two years at Manchester United and a forgettable season at Middlesbrough and he quietly slipped away. AFP

Loris Karius was never regarded as one of Liverpool's greatest keepers before the 2018 Champions League final defeat to Real Madrid. And his two huge errors in that final mean he won't get another chance. He was shipped out on loan to Besiktas in Turkey and his reputation remains largely in tatters. Quite a fall for Liverpool's former No 1. Getty Images

Roberto Jimenez played for a host of clubs in Spain before a move to Premier League West Ham in 2019 where he was used as back-up to Lukasz Fabianski. When he finally had a chance it all went wrong with goals flying in from all angles - many of them his fault. He moved back to Spain - on loan to Alaves and subsequently conceded six against Celta Vigo. A career heading in the wrong direction. Getty Images

Mark Bosnich was signed by Manchester United as a successor to all-conquering keeper Peter Schmeichel in 1999 after impressing at Aston Villa. His professionalism was questioned by manager Alex Ferguson, while pundits lamented his poor kicking. He lasted just 23 matches and managed only a further 17 elsewhere as his career quickly fizzled out. Allsport / Getty Images

Stoke City's Jack Butland was the great hope of English football as far as goalkeepers were concerned as he was linked with a host of top clubs and made his international debut. Fast forward a few years and he's struggling near the bottom of the second tier and has come in for plenty of criticism. Action Images via Reuters

Richard Wright, left, appeared to have a huge career ahead of him. Having finished fifth in the Premier League with Ipswich Town in 2001 he was pushing to become England's No 1. A move to Arsenal to replace David Seaman was a disaster, a spell at Everton wasn't much better, and he only played more than 15 league matches in a season once in the final 13 seasons of his career.

Scott Carson was a blossoming young keeper whose career peaked with England caps. A high-profile error against Croatia in 2007 marked the start of the decline, and while he enjoyed a couple more seasons in the Premier League and in Turkey, he then spent the rest of time in the second tier in England bar a loan move to Man City. Promised much, but didn't quite deliver. AP

David de Gea looking forlornly at the ground after a fumble resulted in a goal has become a familiar sight.

The Manchester United goalkeeper was at fault for two of Chelsea's goals in his side's 3-1 defeat in the FA Cup semi-final at Wembley on Sunday.

And the calls are growing louder for the Spaniard to be moved on.

Just two years ago he was regarded as one of the world's best, a master in his penalty box with incredible reflexes and the ability to pull off remarkable saves with both hands and feet.

Fast forward and he has become a liability, with soft goals slipping through his hands with regularity and questionable positioning leaving United's defence exposed.

He may not be finished just yet - he''s only 29 after all. But the decline has been fast, and United's patience is surely wearing thin.

Before de Gea there's been plenty of other keepers who slipped from being on top of their game to obscurity. Check out the slideshow at the top of the page.

Andy Mitten's United v Chelsea player ratings

David De Gea. 3. Howler of an error for Mount’s goal. Good save from Giroud – after conceding a sloppy one from Frenchman. PA

Aaron Wan Bissaka 5. One of many who struggled in United’s changed system. Taken off. Reuters

Brandon Williams 4. Sloppy. Howler for Mount’s goal. Supposed to support attacks. Didn't. PA

Harry Maguire 4. Puts his head where it hurts and had the bandage to show for it. Did that unbalance him? Scored an own goal. Reuters

Victor Lindelof 5. Poor for Giroud’s opener. Needs to do more to convince that he’s going to be a long term centre half. EPA

Eric Bailly 5. A sad sight watching him stretchered away after a passive first half from United. Unlucky. AP Photo

Fred. 4. As ineffective as the whole team. Won’t be happy with that. Like every fan then. EPA

Nemanja Matic 5. Found it difficult in changed system to match Chelsea up. More success for Chelsea in the FA Cup than he’d had with United. Reuters

Daniel James 4. If you get a chance you have to take it. Didn’t. Has to prove he’s good enough to play for Manchester United. Reuters

Bruno Fernandes 6. Best of a bad bunch. Always wants the ball. Cool on the penalty. AFP

Marcus Rashford 5. Poorest game since resumption of football. Limited service to him, but he offered limited movement too. EPA

SUBS: Anthony Martial (45+2') 5. One week a 10/10, the next anything but. Failed to affect game. AFP

Paul Pogba (55') 5. Chasing a game, chasing shadows. AP Photo

Mason Greenwood (56'). Top young player. But not today. EPA

Timothy Fosu Mensah (79'). Second appearance in three days after three year absence. Reuters

Odion Ighalo 6 (79'). Worked hard. Offered something different in limited time. Getty Images

CHELSEA: Willy Caballero – 7. Few saves to make but was alert to any dangers and quick to come off his line to clear up balls over the top. Had the occasional flap at crosses and couldn’t do anything about the penalty. Getty Images

Cesar Azpilicueta – 8. Lovely low cross to set up Giroud’s opening goal and was untroubled on the right side of the three-man defence. Getty Images

Kurt Zouma – 8. The Frenchman can blow hot and cold but at Wembley he was certainly on his game. Reuters

Antonio Rudiger – 8. A reminder of how good he can be. Solid as a rock at the back (save for one clumsy challenge on the edge of the area). Forced Maguire’s own goal for Chelsea’s third. AFP

Reece James – 7. Handled his defensive duties well and ran the right channel all game. EPA

Marcos Alonso – 8. How can one player be so ordinary at full-back and absolutely superb at wing-back? Introducing Marcos Alonso. AFP

Jorginho – 6. Plenty of typically nice, short passes and touches but didn’t impose himself fully on the game. The Italian didn’t need to playing alongside Kovacic. Reuters

Mateo Kovacic – 8. Bossed the midfield. Drove his team up the pitch, always in space for a pass, and ran all day to provide a presence in defence and attack. Getty Images

Mason Mount – 7. Doubled Chelsea’s lead right after the break, although the goal owed just as much to a De Gea blunder. Full of high pressing. EPA

Willian – 6. Quiet game from the Brazilian on the attacking front but always offered an outlet and tracked back fulfill his defensive duties. PA

Olivier Giroud – 8. Neat finish to score the opener to continue his fine form since the restart. EPA

SUBS: Tammy Abraham (80’) – 5. Had little time or opportunity to impact the match as Chelsea looked to close out the victory. Getty Images

Callum Hudson-Odoi (80’) – 5. Produced a nice, jinxing run in injury time, but also conceded the penalty that gave United their consolation goal. Getty Images

Ruben Loftus-Cheek (86’) – N/A. Reuters

Pedro (90+1’) – N/A. EPA
