Look at above comment regarding Lewis.
Doku will probably play on the right some games, but I don’t see the Mahrez comparisons, he is more explosive and right footed.
In fact Mahrez got replaced by Bernie last season because Pep wanted more of a midfielder on the RW.
And with the sale of Palmer (wide RW a like for like Mahrez replacement) and how we are using Walker, I’m just convinced that will continue. With the LW being the main 1v1 dribbler spot, which Doku is tailor made for.
Stones is brilliant in that we will still use an inverted CB like Newcastle, but if we don’t, he is still brilliant in a wide RCB role.
