Xhaka and Mustafi definitely had a supposed higher pedigree when they came.
My concern with Xhaka is that he's looked the most consistent I've seen him at anytime under Arteta than those years under Wenger. Now wether even this consistent version is good enough is another question.
I don't have time to find the reports but we essentially ended up overpaying for Mustafi as we dragged the deal till mid-august and Valencia would only sell for a bigger fee as they had very little time left in the market. Earlier he was going to sign for around 25m.
The entire transfer spend in the last 4-5 years under Wenger bar 1-2 players was disastrous.
Spend 16m on Welbeck and then another 16m on Perez. This at a time their combined cost could buy a capable player.
Wasted 2015-16 by not buying an outfielder or competition for Giroud.
I don't think as badly of Debuchy here prior to his injury as some but when he came back after his long injury he was done at the top level.
Chambers 16m barely played here and his RB experiment over after being given the run around by that rat from Swansea.
Paulista, Mkhitaryan, Lacazette, Sokratis, Torreira, Lichsteiner, Suarez, Geundouzi, all not worth their money or complete successes.
Only 2- Auba and Leno.
