I'm not sure I even understand what this means? I can only assume you are referring to R Bennett, Andreu and Lafferty? Possibly E Bennett, but that can't be right. Who are the other five/six? It seems to me that we would never get rid of R Bennett (given our CB options...) and it's pretty obvious the club has been trying its hardest to offload Lafferty and Andreu, but you can't force these moves.
I'm pretty happy with our back-up options - our bench and full squad looks stronger than it has ever been in the last five years. I accept that the first team has not been strengthened as much as I'd hoped, but that's because to improve on virtually every position we needed to shell out £7m plus and we simply don't have the money for lots of that, nor does it seem players in that bracket really want to come to us too much.
Rather than worrying about the squad, we clearly can compete in this league, we are a better team than c. 5 others in the PL and therefore have every chance of staying up with the squad we've got. Of course, I'd love it if we signed a couple of classy players, I just don't see it happening and I don't think it will necessarily help us stay up all that much more (look at Mings getting injured for Bournemouth - same could happen for us...)
