Agree with you Max, another good aspect is if he say starts with Sanchez right and Lingard 10, he can always swap them around if its not working, so saves on using a sub straight away when they are both comfortable in either position.
I think after the summer, 433 will be his preferred away day formation against the big boys, I can see him going big in the summer for either Ozil/Dybala or if not of them then a right winger with pace to burn and move Sanchez inside.
Also, can see a huge CM coming in, talk obviously about Carrick retiring and Fellani going on a free, plus question marks over Herrera at the moment so your thinking he might need 3 CMs.
Vidal Free
Saul 60m/70m ish
Decent back up DMC for Matic
Personally would have TFM as back up to Valencia, think 2 MOTM performances in his last 3 games at RB, LB Young and Shaw, concentrate on that 10 or RW and CM in the summer for me, maybe a back up striker as Ibra will be gone.
