Could be the other way around - Flamengo aren't interested in a 'loan now, buy later' deal, so we're now having to big up Mustafi in case that's what we're left with?
Yes. Honestly, the next time we redesign the logo we should consider going with a guy in coach's outfit polishing a turd - it wouldn't be too far from the truth.
Slightly different with Wenger though, as he was a manager and had total power over recruitment - Arteta and Emery have been hired as coaches, and their job is to get the most out of the players they have. They can, of course, ask for better, but that will be done in private - in public, you keep the players you have confident and motivated and fighting for you (right up until the very moment before you hand them their p45).
