As far as Sundays go you would be hard-pressed to top Harvey Elliott's.

The 16-year-old player signed for boyhood club Liverpool in the morning and played his first minutes for the side in a pre-season friendly against Napoli in the afternoon.

“I can’t wait to get started and it will be a truly special feeling to pull the famous red jersey on," Elliott said on Instagram, accompanied by a picture of him putting pen to paper on his first Liverpool contract. "I’ll work as hard as I possibly can for the club and I feel Anfield is the perfect place for me to develop and progress as a player.”

Which clubs were trying to sign him?

It is something of a coup for the European champions, with Barcelona, Real Madrid and Paris Saint-Germain only some of the clubs reportedly keen to sign the England youth international.

Elliott’s schoolboy terms at Fulham expired at the end of June, and though the Londoners, who were relegated from the Premier League last season, were keen to tie him down to fresh terms, a move to one of Europe's heavyweights always looked on the cards.

Neither party disclosed any financial details of the deal, but multiple reports have said that Fulham could be due as much as £6.5 million (Dh30m) in compensation from the Champions League title holders.

Why is he so special?

Elliott already has a couple of records to his name, including the youngest Premier League debutant after appearing for Fulham against Wolves in May at age 16 years and 30 days, beating the record set by fellow Fulham player Matthew Briggs in 2007. He made his Fulham debut in the 3-1 League Cup win over Millwall in September at the age of 15.

Elliott has represented England at youth level, scoring three goals in two games for the Under 15s but has not scored in six caps for the U17s.

Though Elliott's transfer has set tongues wagging, it is likely, initially at least, that he will continue his development with Liverpool's U23 and development squads.

What are people saying?

"A sensation" was Fulham captain Tom Cairney's description of the fleet-footed youngster. Another former teammate, Ryan Sessegnon, who at 19 is another product of the Craven Cottage youth team and predicted for a mega move to one of Europe's top clubs, responded to Elliott's Instagram post with the message: "Congrats lil bro keep pushing."

"He came here, he decided for us," said Liverpool manager Jurgen Klopp after Sunday's 3-0 defeat to Napoli in Edinburgh. "He could have gone pretty much everywhere but he wanted to be part of Liverpool."

What's his playing style?

If his man bun hairstyle is anything to go by, Elliott is not a teenager short of confidence. His playing style is likened to that of another jet-heeled left-footed winger, Gareth Bale, whom Elliott is reportedly a fan of.

Let's hope his move to Liverpool doesn't sour like the Welshman's has at Real Madrid.
