The deeper one looks into the squad, the more adequate it appears to be, particularly if a player or players are only coming into the team as temporary replacements through suspensions and small injuries. But what happens when half the team are decimated through illness..? Truth is, I don't think any club can adequately cover for that. Personally, I don't think we should be looking to cover or backup positions, rather that we need to strengthen the first team proper. Whoever is displaced becomes cover for that position [eg, Jack Cork]. It's possible that Boruc could get some proper competition, but that's about it on the back up policy, as far as I'm concerned. Where to strengthen..? I don't know. At present there are no obvious weaknesses in the side, unless you say that they could all be improved. Maybe Astori and Banega..? I certainly wouldn't be buying players to automatically become 2nd in line. That way lies mediocrity.
