Yeah, we have enough fringe - we need more short back and sides! Wait... that sounded a lot funnier in my head. Anyway.
We have a squad of backup players, so signing more backup players doesn't make a lot of sense, particularly young ones where we have players coming through from the youth/reserves. Having said that, we do need a more defensive midfielder as a backup to cover for Lucas and Gerrard if we intend to play with two holding players and 2 wings. Gerrard was injured a lot this season, and we really struggled when Lucas was running on empty. Ideally Spearing will continue to improve, which is why I was okay with the interest in Scott Parker. At his age he wasn't a guy who would keep Spearing out the team, and could act as a mentor in many ways. Adam is more pass-arific, which we need in a backup midfielder as well. But anyone "up-and-coming" in this position makes no sense.
I also think that being in for Scott Dann is settling for second best, unless we're getting him in addition to a Sakho/Cahill.
