I'll try to be as objective as I can. Starting from a 5/10 (a transfer window where the team is equally strong as the season before):
Defense: Considerably stronger ( I rate Gvardiol much higher than Laporte). +1 6/10
Midfield: before KDB, slightly weaker (Kovacic is a 8.5/10, while Gundo is a 9/10). After KDB's injury, considerably weaker. -1 5/10
Forwards: Lost Mahrez whois not a starter but a very important rotation member and a big goal threat. Slightly weaker. -0.5 4.5/10
Fees for outgoings: We got 55m for Laporte, Mahrez, Cancelo and Gundogan (I know his contract expired). That's poor, especially with Saudi money buying for very inflated prices. -1 3.5/10
Fees for incomings: Kovacic is a steal, and Gvardiol for a pretty fair price. +1 4.5/10
Fees for Academy: Here is the best part of the summer. Great fees all over the place. We have a fantastic net spend thanks to this. +2 6.5/10
Squad size: We have 2 fewer bodies than last season (and last season we already had a somewhat thin squad). -1 5.5/10
- If we add that we haven't been able of selling Phillips (his value will drop even further if he plays as much as last season, which seems to be the case), weren't able to bring Bellingham (it happens, so no big deal), and have had a relatively slow reaction to KDB's injury, I think a 5/10 transfer window is pretty fair.
