Spurs faced Newcastle United in the Premier League yesterday where the visitors snatched a late point in a 1-1 draw.
During the game, Son Heung-Min was forced off at half-time with a hamstring injury.
Tomorrow, Spurs face the Blues in the second of four games in the space of eight days, finishing off their hectic run with meetings against Maccabi Haifa and Manchester United prior to the international break.
Last week, Tottenham were handed a bye in the competition after several Leyton Orient players tested positive for coronavirus.
Ahead of tomorrow’s London derby, here is a look at the latest Tottenham injury news.
Son was replaced by Steven Bergwijn at the break after sustaining a hamstring injury.
Although he was brief on his answers after the game, Mourinho is not expecting Son to return to action any time soon.
The South Korean international had injury troubles last season and can expect another lengthy absence, albeit with an unknown expected return date yet.
It is fully unknown as to when Bale will be fit enough to make his second debut for Spurs.
The Welsh forward is not fully fit after facing an injury-hit 2020 so far but last week, Mourinho admitted that the Real Madrid loanee was determined to become fully-fit as soon as possible.
“I don’t know when Gareth can be back. The only thing I know is that his motivation is high,” he said.
“He’s so happy to be with the club of his heart, he’s so happy to play for us. And when a player has this motivation, many times you can shorten the period of recovery, you can shorten the period of getting fit and ready to play.
“We want to help him so when he’s available to train with the team, we’re more than happy to have him and help him back to a level that made him one of the best players in the world.”
Joining Bale and Son in the treatment room is defender Japhet Tanganga who currently high as thigh injury.
Again, Tanganga’s current progress is unknown, with the defender yet to feature in a matchday squad this season.
