(Reuters) - Benfica forward Roman Yaremchuk was left frustrated after spurning a number of opportunities against former side Dynamo Kyiv as the teams played to a 0-0 draw in their Champions League Group E opener on Tuesday.

Ukraine international Yaremchuk had the best chance of the game when the ball fell kindly to him on the edge of the six-yard box, but his shot was saved by the legs of home goalkeeper Denys Boyko.
