In FM, before buying an important player, I check their injury history. If a nobody like me can take 5 minutes to check something like that then Maybe United should, you know, check on small things like that before buying. Do the diligent work.
I wouldn't buy Neymar for example. I don't care how good he is. I need my players to actually be able to play at like 85% of my matches.
Gabriel showed the intention of going forward. Joelinton was only helping him get there faster. That's all.
