I think it is crucial to poch's system that we have a winger with pace and has somewhat of an end product on the bench that we can put in as a sub to open things up. Unfortunately, Lennon and Townsend cant play that part because one is convinced he's the 2nd coming of bale when he's not even close to the poor man's gareth bale and the other offers nothing going forward. I think thats what makes getting walker back even more crucial as we can push him up more than naughton or dier.We need pace everywhere and don't have nearly enough of it. Obviously pace without end product isn't ideal, but we need to be able to stretch teams. At the moment opponents can push up on us, knowing we're not going to get in behind them too often and they can also sit in like West Brom, knowing we have difficulty breaking teams down.
You're right though, pace out wide and from the fullbacks is crucial for us since Poch doesn't want to play with any traditional wide men.
