Man City below their best in Champions League win, says Pep Guardiola

Raheem Sterling hit a late winner as an unusually subdued Manchester City secured top spot in their Champions League group with a narrow victory over Feyenoord.
City - by their recent high standards at least - produced a flat performance at the Etihad Stadium but Sterling's sublime 88th-minute strike proved the difference in a 1-0 win.
