Scott McTominay of my favourite players in the squad and he is certainly in my preferred starting eleven, as he has been for several seasons now.
I like his passion, work rate and attitude.
Buying a specialized 6 and playing Scott McTominay as a box to box 8 should be a priority, as that is his best position.
Him and Fred should be rotated with Matic and Vdb this season in order to keep them all fresh for the most important games.
Matic and Vdb are easily good enough for most games, especially when Pogba is on the left as well, as that is almost like having an extra midfielder rather than a left winger or left forward.
