His crossing was today I would agree. But his put in some beauties recently and if you look back to his other games he's a good crosser.
The problem is crossing is low percentage, another thing I bang on about. A team that crosses loads and scores loads from them is City, but look at the positions they take them from, not from out wide but from the edge of the 18yrd box, usually De Bruyne to the back post. The other they do brilliantly is from the goal-line and then pull it back to a player running in behind Jesus, Aguero who draw the defence.
From out wide, they are really easy to defend against, unless you have Vertoghen trying to stop them!!!
