Spurs were 12 points behind their west London rivals when Mourinho replaced Mauricio Pochettino as manager just one month ago, but they are now only three points behind and would go ahead of Chelsea on goal difference with a win here.
Having looked near certs to finish in the top four under Frank Lampard this season, the visitors have lost four of their last five league games in a disappointing run of results.
Tottenham, on the other hand, are loving life under Mourinho, having won five out of seven matches in all competitions under his tutelage so far, with one of the two losses coming in a Champions League dead rubber at Bayern Munich.
As such, the bookmakers narrowly expect them to grab the three points here.
Tottenham are 11/8 to win, with the draw 11/4 and a Chelsea win 7/4.
A close game is certainly predicted, then, as are goals.
Both teams to score is just 1/2, and it has landed in six of Mourinho’s seven games at Spurs so far.
It’s also landed in seven of Chelsea’s eight away games in the Premier League this season, so the short odds are perfectly fair for two sides who have attacking talent in abundance but have looked open defensively throughout the campaign.
With the form guide and likelihood of goals weighed up, Tottenham to win with both teams to score seems a reasonable bet at 11/4.
Dele Alli has been rejuvenated under Mourinho so far, and historically has an excellent record against Chelsea with five goals and two assists in his last five Premier League games against them. At 13/5 to score anytime, he’s excellent value.
England strikers Harry Kane and Tammy Abraham will face each other here, and are 13/10 and 6/5 respectively to get on the scoresheet.
Wingers Lucas Moura, Son Heung-Min and Christian Pulisic are 5/2, 9/4 and 13/5 respectively.
