So, according to you this summer we should have bought:
1. Top quality right back (check)
2. Top quality center back (check)
3. Right winger (we've signed potential there - check. You may not fancy him, but I'm sure you weren't happy with Chicharito as well. That was a similar signing in all respects. Unknown, young, filling in an important gap. Lots of potential.)
4. Central Midfielder to replace Herrera / Matic. (Looks like Ole is relying on McTomminay to make the step up, and hoping for one more signing).
To summarize, your frustration is that the club has filled the most gaping holes first, and is relying on a few academy products. Do you see the irony of this? We are not winning the league this season, and if you don't want to give potential a chance now, I don't see when you will. The club have definitely done enough good business to get into the top 4 (I would include keeping Pogba at the club as a massive plus on this one as well).
