Dembele needs to pass faster first-time and stop dwelling on/dribbling with the ball all the time. Same with our other players except Holtby, though Bale gets more leeway since he's capable of those individual goals. We're missing out on seeing opportunities here because we take so long to figure out what to do with the ball and our passing tends to slow down play by forcing the receiver to readjust his body rather than keep running along the same momentum. It reminds me of Liverpool last season, except for less possession in the final third - lots of passing, no real target in the box, loads of shots but very few CLEARCUT chances created thanks to the slowness of play.
I think it's general team issues like that that are a bigger problem than individual performances (lack of a smart striker aside). Having said that, Lewis will look better and better the more familiar he gets with his teammates, and Ade's return will help.
Good points. And Mumorn made some good points, too
