Genuinely absolutely buzzing with this. I love Jack, I love Foden out wide and I loved Mahrez.
But all have their limitations in the sense of not being able to burst at their fullbacks (Phil can do it centrally) with skill, pace, power and precision the way Doku seems to be able to.
It'll be so exciting to be able to use him. Methodical, position-based wingers aren't working in a game? Fuck it, bring this guy on and let him run ragged.
The way Pep used Walker on Saturday was a pointer to getting a winger with pace IMO. Gameplan was built around getting space on the right-hand side.
