The Portuguese, who was in charge from December 2019, had his last game in the 2-2 draw with Everton on Friday night.
The sacking comes less than 24 hours after Tottenham announced they were part of the hugely controversial Super League and, therefore, this could be seen as a case of the club attempting to bury bad news.
And letting go of Mourinho is undeniably bad news for the club’s hierarchy given the huge expense of hiring him – the 58-year-old is believed to be earning close to £12m a year – and the fact that he arrived as a replacement for Mauricio Pochettino, who was incredibly popular with the fanbase having led Tottenham to consistently high finishes in the Premier League and to the Champions League final in 2019.
Mourinho has now been sacked by three different clubs in England – Chelsea, twice, Manchester United and Spurs.
Spurs take on Southampton in the top flight on Wednesday evening, with their next fixture following on Sunday as they face Manchester City in the Carabao Cup final at Wembley Stadium.
Assistant coach Ryan Mason and Chris Powell, who is head of coaching at Tottenham’s academy, are expected to take over for the remainder of the season.
