Why not? If he comes good we may not even need new reinforcement in CM. Mctominay is our best midfielder this season, Fred is finally settling and is like a new signing, and Mejbri sounds like a special talent, why not just start him? Fabregas is playing regularly for Arsenal at similar age too. Who knows if we are lucky he could be a good option for us. Then we have Pogba, of course, we never know where he wants to go in Summer. So, we probably only need to replace Pogba, which is also the hardest part.
