29-year old Ryan Mason replaces Mourinho as Tottenham's interim manager
He will be the first manager under the age of 30 to take charge of a team for a Premier League game.
Ryan Mason will lead Tottenham into the English League Cup final against Manchester City on Sunday as the youngest manager in the club's history after being installed as the replacement for the fired Jose Mourinho until the end of the season.
The 29-year-old Mason retired from playing in 2018 on medical advice after failing to fully recover from a fractured skull following a clash of heads during a Premier League game the previous year.
He has been working with Tottenham's academy's players but was given the top job on Tuesday for the remaining month of the season following Mourinho's departure on Monday.
He took first-team training on Monday after Mourinho's departure.
Mason's first game in charge will be against Southampton in the Premier League on Wednesday, before the cup final against City at Wembley Stadium on Sunday.
He will be the first manager under the age of 30 to take charge of a team for a Premier League game.
The club also confirmed that Chris Powell and Nigel Gibbs will be interim assistant head coaches, with Michel Vorm as interim goalkeeping coach while Ledley King will continue in his role as first-team assistant.
Tottenham is in seventh place in the league, five points behind fourth-place West Ham in the race for Champions League qualification.
That could be irrelevant, though, since Tottenham is one of the six English teams who have agreed to join a breakaway Super League, which could begin as early as next season.
"We have great belief in this squad of talented players," Tottenham chairman Daniel Levy said.
"We have a cup final and six Premier League games ahead of us and we shall now focus all our energies on achieving a strong finish to the season."
