Nathan Ake was on target as Man City edged Arsenal out of the FA Cup with a slim 1-0 win at the Etihad Stadium which saw Pep Guardiola reunite with his former assistant Mikel Arteta.

In a fourth-round battle between surprise Premier League leaders Arsenal and a second-placed City side who are clinging to their coat-tails in the top flight, it was defender Ake who made the difference on Friday.

He delivered the breakthrough in the 64th minute, with a sharp side-footed finish finding the bottom-right corner, out of the reach of goalkeeper Matt Turner.

The top two have still to meet in the Premier League this season, with this tie a taste of what is to come when those games take place in February and April.

Guardiola’s City began strongly, but Arsenal had a big chance in the fifth minute when Takehiro Tomiyasu’s powerful strike from just inside the penalty area was palmed away by Stefan Ortega.
