It's quite the obvious problem.. Not only are we always playing the same stereotype sideways passes. We're also playing them, like really really slowly. Take 2-3 touches, maybe 2-3 more and then release the ball. If we had 2 extra midfielders who could play some one- or two-touch football, we'd maybe get the ball upfront before everyone gets double marked.
And Kulu is a passer first. He's not the greatest of dribblers like Douglas Costa so he needs more movement upfront as well. Surely we'll give him another season.
