No they didn't. Piss off.
Aww, don't be trigerred. I rate Pogba, but he was nothing special last year and went through phases of underwhelming performances. Had a few top draw performances.
Gundogan was never underwhelming, but his peak wasn't comparable to Pogba's. Just because Pogba is the crown jewel at United, doesn't automatically mean he was the best midfielder last year.
Midfielders who were better: Silva, Fernandinho, De Bruyne, Kante.
Comparable: Gundogan, Matic, Coutinho before he left.
Its certainly a loss to them, it would be to any team. However, they are very well equipped to deal with it. No side in Europe can call upon Gundogan/B Silva's level of player when a startig 11 midfielder gets injured. Both were, in very recent history, stars of teams having stellar league and CL campaigns in Europe's top 5 leagues, and have been pretty good in their time in England.
