Nathan Ake was Manchester City's unlikely match-winner in their 1-0 victory over Arsenal in the fourth round of the FA Cup, helping his side to perhaps land a psychological blow on the Premier League leaders ahead of their top-flight clash next month.
Mikel Arteta prioritised Arsenal's title challenge with his team selection, resting six regulars for the trip to the Etihad, but a strong City XI struggled to find a way through until defender Ake passed the ball into the bottom corner (64) after sub Julian Alvarez had struck a post.
Guardiola had appeared less than impressed with his side's first-half performance, which saw Leandro Trossard catch the eye on his first Arsenal start and ended with John Stones appearing to suffer a hamstring injury. But the City head coach eventually got the better of his former assistant Arteta as the home side edged through.
