I agree with Sanson showing quality.
Also think its difficult for Gerrard to pick out a midfield 3.
We got Mcginn, Luiz, Sanson, Ramsey (can also say Chuk?).
Only Luiz suits the DM style (even though he isnt perfect for it).
By playing Sanson we hamper the development of Ramsey/Chuk. I feel Sanson is fighting with Mcginn for a spot.
