Your opinion aint far wrong.we're not playing with enough pace on occasions to create opportunities for our forward to run into the space either behind their back line or between their back four and midfield; it's all too slow and predictable hence why we have problems to break down teams of late. Just a personal opinion.
Its very easy for the opposition to set themselves against us when we atttack.
More urgency and zip is needed
Clucas and Robbo combine well on the left (usually) but Sam has looked a bit below par in recent games. However, I'd still play him ahead of Aluko + with Maloney still injured, he gets the nod IMO.
