Tottenham Hotspur have parted ways with coach Jose Mourinho less than a week before the Carabao Cup final against Manchester City, according to several reports.
Ryan Mason will take charge of first-team training on Monday, the club said in a statement, and a further update will follow in "due course".
"The club can today announce that Jose Mourinho and his coaching staff Joao Sacramento, Nuno Santos, Carlos Lalin and Giovanni Cerra have been relieved of their duties," a club statement said.
Chairman Daniel Levy said: "Jose and his coaching staff have been with us through some of our most challenging times as a club. Jose is a true professional who showed enormous resilience during the pandemic. On a personal level I have enjoyed working with him and regret that things have not worked out as we both had envisaged. He will always be welcome here and we should like to thank him and his coaching staff for their contribution."
The news comes the morning after the London club said it was one of 12 clubs forming a breakaway European Super League.
Former Porto, Chelsea, Inter Milan, Real Madrid and Manchester United manager Mourinho had been in charge of 86 games at the club, leading them to a sixth-place finish in the 2019/20 campaign.
Mourinho, 58, replaced Mauricio Pochettino as Spurs head coach in November 2019 but has struggled to get the best out of a squad packed with quality and is reported to have fallen out with several prominent first-team players.
Spurs are currently seventh in the Premier League and in danger of missing out on a top-four finish. They were knocked out of the Europa League at the last-16 stage last month. Mourinho's last match in charge was Friday's 2-2 Premier League draw against Everton.
The North London club contest Sunday's League Cup final against City at Wembley hoping to clinch a first trophy since 2008.
