I think the attraction of Walker is that he offers something a bit different to the players we have. It's last seasons playing of today's match that I most remember him for (Yes I know we lost, but that was an absolute travesty). His direct running at the defence terrified the Plymouth players, and he should have had a penalty in the first few minutes of the game. For the rest of that game he terrified their defence until, I think I'm remembering correctly, he was subbed toward full time; and he showed that same level of commitment and drive in the other games he appeared for us (well... the ones I saw/heard anyway) Essentially, he's an absolute nuisance, that keeps his fullback under pressure constantly, mixes his game up by showing short and making good, intelligent runs and when the ball's on the other flank he's busting his gut to get in a goal scoring position. With Lowery now starting to show signs of the playmaker we know he can be, with a range of passing to match, it's a mouth-watering prospect in my humble opinion. as to who would make way? I don't think it's a case of anyone particularly making way. I think it's about options to change a game. Powell seems to be struggling this season (although he has had a couple of good games playing from the left. I also wonder if he's an option to deputise for Mikael if he gets injured or fatigued), Charlie is the very definition of 'mercurial' and Owen can't be expected to perform at his current level all season (if he does he won't be here much longer either. Overall, Boro are not going to want to send him out to warm a bench again - agreed, but I do think they would be happy for him to come back to us, given his brief, but successful, spell here last season.
