Agree, the main changes so far were necessary and more or less like-for-like. However, I feel some uneasiness because we seem to have let some people go without replacement.
Apart from the King/Vertonghen change, we seem to have elevated Caulker to replace both Dawson and Bassong/Nelsen. While King's unusual situation may have been the reason for a fifth CB, at the same time we have let our obvious emergency CB leave (Corluka) and the other may also be out this season (Huddlestone). Who would be emergency CB for us now (Walker, Sandro?).
As well as Kranjcar, Pienaar has also gone. With Modric gone, our left sided options to replace Bale have become severely reduced (to Townsend and Rose?). Signing Willian would have course solve this problem.
And we haven't replaced Pavlyuchenko or his temprary replacement, Saha. So another youth player is elevated to replace an established player unless we do business this week.
And while we have to assume that we will add to the midfield options with Mountinho or Dembele, it feels at this moment like we have gone from Modric and Huddlestone to Jenas in the non-DM, non-AM CM position (what word describes this CM position?).
Hopefully most of these holes will be filled when the window shuts. It does suggest that we should use the Modric money for more than one player, rather than putting most of it on Moutinho.
