Kevin De Bruyne's perfectly-struck 48th minute goal and a late Raheem Sterling effort gave Manchester City a 2-0 win over Shakhtar Donetsk to make it two wins out of two for Pep Guardiola's side in Group F.
But City's Argentine striker Sergio Aguero missed a chance to equal the club's all-time scoring record when he had a 72nd minute penalty saved by Andriy Pyatov. The miss left him one goal behind Eric Brooks, who scored 177 goals in all competitions.
After a frustrating first half, in which Shakhtar threatened on the break while City were too often unable to find the final pass, Belgian De Bruyne broke the deadlock with a fine right-foot shot from the edge of the area after being well set-up by David Silva.
Substitute Sterling missed a great chance from a low De Bruyne cross but made amends in the final minute when he fired home after good work from Bernardo Silva.
