Join Natalie Pike on Matchday Live with guests Brian Barry-Murphy and Michael Brown to look back at a fantastic victory for the Blues.
City are into the fifth round of the FA Cup!!! A big display at the Tottenham Hotspur Stadium and a deserved 1-0 victory.
The fans have been amazing tonight with 9,000 at the Tottenham Hotspur Stadium and they deserved that.
Nathan Ake with the first goal at the Tottenham Hotspur Stadium and it could be a winner.
Tottenham aren't happy and want it disallowed. Vicario fails to deal with De Bruyne's corner under pressure from Ruben Dias and Ake prods the loose ball home. It's gone to VAR.
We've scored at Tottenham!!!!!!!!!! It's Nathan Ake. Not the prettiest... just a yard out but it's a goal!
