Ake grabs winner as Man City beat Arsenal in FA Cup

Nathan Ake scored the winner to send Manchester City into the FA Cup fifth round with a narrow victory over Premier League title rivals Arsenal.

It was City who shaded a tight contest thanks to Ake's precise 64th-minute finish after good work from Jack Grealish.

Arsenal had chances of their own, especially in the first half when City goalkeeper Stefan Ortega, deputising for Ederson, saved well from Takehiro Tomiyasu and new signing Leandro Trossard.

There was little to choose between the sides and their Premier League battle will come into focus once more when they meet at Emirates Stadium on 15 February.
