I’ve said this in other threads but Onana as CDM only works if we play a double pivot. He’s not good enough to play as a sole DM. Watch him. When he’s the sole DM and he gets the ball facing his own goal, he almost always goes backwards. His first you h isn’t good enough to be able to turn and progressively pass forwards, which is absolutely essential if you have a single pivot. He and Mainoo could work if they both play as 6/8 hydrids in a double pivot system. He’s big and strong yes, but his first touch and play under pressure isn’t good enough to be the only pivot in our midfield. Our build up play will suck.
If we keep Mainoo, Fernandes and Mount - which seems extremely likely. And ship out Amrabat, Eriksen and Casemiro (no idea what will happen with McSauce, I’d sell him - so much FFP upside), I’d personally go for Joao Neves as a priority, with him and Mainoo forming the basis of our midfield. I wouldn’t mind Onana as a second line option to understudy them, but again have concerns about his ability to play as a single pivot, so would probably go for someone like Joao Gomes. Third player would be a really young one with loads of upside like Mastantuouno.
Defensively, Yoro, Diomande, Inancio, Silva, give me any two of those four. Up front, Vítor Roque and Olise. I’m pretty much exclusively looking at young, hungry players, with their best years in front of them, loads of upside, and tons of room to grow. Players on the verge of stardom, but not quite there yet. Already playing at a high level. Wirtz is the ultimate dream, but that isn’t happening this year, and likely never. And in the right system, with a good coach, I think we are blessed to have Fernandes and Mount rotating as 10s. We need a left back too. Not to replace Shaw but to rotate with him. Someone under 23, good enough to start and with lots of potential to improve.
Neves is the one though. Fabulous player. Going to be brilliant. Him and Mainoo together, two proper footballers. Would love to see that.
