Jose Mourinho has been appointed as Tottenham's new manager following the sacking of Mauricio Pochettino.

Former Chelsea and Manchester United boss Mourinho has signed a contract until the end of the 2022-23 season.

Tottenham chairman Daniel Levy, announcing Mourinho's arrival, said: "In Jose we have one of the most successful managers in football. He has a wealth of experience, can inspire teams and is a great tactician. He has won honours at every club he has coached. We believe he will bring energy and belief to the dressing room."

Mourinho said: "I am excited to be joining a club with such a great heritage and such passionate supporters. The quality in both the squad and the academy excites me. Working with these players is what has attracted me."

A Spurs statement read: "Jose is one of the world's most accomplished managers having won 25 senior trophies.

"He is renowned for his tactical prowess and has managed FC Porto, Inter Milan, Chelsea, Real Madrid and Manchester United.

"He has won a domestic title in a record four different countries (Portugal, England, Italy and Spain) and is one of only three managers to have won the UEFA Champions League twice with two clubs, FC Porto in 2004 and Inter Milan in 2010. He is also a three-time Premier League Champion with Chelsea (2005, 2006, 2015)."

The 56-year-old Portuguese won three Premier League titles over two spells in charge of Chelsea and returned to England to manage Manchester United in 2016.

He was sacked last December following a poor run of results and has been out of work since, most recently working as a pundit for Sky Sports.

Pochettino was dismissed after five-and-a-half years in charge, less than six months after he took Spurs to the Champions League final, with the club lying 14th in the Premier League table after the opening 12 matches.

Mourinho, who also managed Porto, Real Madrid and Inter Milan, has turned down a number of opportunities to coach abroad, including with clubs in China, Spain and Portugal, since his Old Trafford exit.

His first match in charge will be the London derby away to West Ham on Saturday.

Spurs and England forward Harry Kane paid tribute to Pochettino, saying "you were my manager but my friend as well".

The striker posted on Twitter: "Gaffer. I'll be forever thankful to you for helping me achieve my dreams.

"We've had some amazing moments in the last 5 and a half years that I will never forget.

"You were my manager but my friend as well and I thank you for that relationship. Good luck with your next chapter!"

Spurs are 14th in the table as Mourinho takes over and former England manager Sam Allardyce believes he can get them back into contention for a place in the top four.

Allardyce told talkSPORT: "There were often questions that because he lived in the hotel at Manchester United that was one of the problems, because he was away from his family.

"He's back with his family, back in London, where he loves, and he's back with Tottenham, which is a massive club for him to get his teeth into and try to get them winning some trophies.

"Certainly he's got the talent and quality of squad to make Tottenham a big challenger and I think they can still challenge for the top four."

Former Tottenham manager Harry Redknapp also expects Mourinho to make an immediate impact.

Redknapp told BBC Radio 5 Live: "Pochettino was excellent but the same voice after six years starts to wear a little bit thin. People get used to the same message.

"But the same players, a new face comes in - he probably hasn't got to do anything clever or different, just give them a bit to get them going and they'll find another 10 per cent on Saturday at West Ham.

"They'll find a spring in their step knowing their jobs are under threat now (because) Mourinho has got to be ruthless. If he doesn't like what he sees he'll bomb them out and bring in people he wants."
