I am looking at our squad and I see 5 slots that Wenger will need to replace/upgrade. Sagna, Squillaci, Arshavin, Coquelin and Diaby (who will miss all next year, even if he comes back). There are no home-grown issues (I think).
So 2 defenders, and 2 midfield and an attacker.
So then we look to the youth team and we don't see too many that are ready to move up to a permenant place on the team (obviously we can still play them). A year from now, to replace Arteta and Rosicky maybe is more realistic.
So what do we need? A right back and a CB for sure. It would be nice if at least one of them could do both.
Two midfielders, both capable of playing in the 2 deeper positions.
One striker who can play in the middle.
So, I think we need 5 signings. If they are first 11 standard, those of you looking for a huge upgrade of the team, will get your wish. That is nearly half the team. However, I think it is likely that the CB will be young and inexperienced. I can't see a CB coming in and dropping Per, Kos, or TV down the line-up.
But I CAN see the other 4 starting on the first day of the season. Let us assume that Wenger does have 70M to spend. 5 players, hmmm, that 70M doesn't look so good now.
Let's assume he can get the 4th choice CB for what he can get selling fringe players, and also assume that he will not be a big name. Sorry, to the "Our defence is ****" crew.
Up front we need an expensive striker, so let's budget 25M-30M for him; 10M-20M for the other 3. So we're not going to get any of the really big stars.
I would say the names we are looking at are:-
Striker - Robert Lewandowski, Ãlvaro Negredo, Pierre-Emerick Aubameyang
Midfield - Etienne Capoue, Milan Badelj, Pirmin Schwegler, Morgan Schneiderlin, Maxime Gonalons, Asier Illarramendi, Stefan Reinartz, Cesc Fabregas
Defense - who knows? There are a lot of defenders out there.
