He’s undoubtedly an articulate chap with good ideas. But the reality is that the formation he wants to play with will be quickly sussed by the better sides who can play around it - especially with the number of square pegs in round holes. Lingard is obviously a useful player, as is Alli, but neither are really central midfielders in the same way that Walker isn’t a centre back. It’ll be a learning curve for him for sure, I just hope he tries to find players that better suit his system.
