Ajax is the odd approach and what he did with Ajax largely matches with their ideals. So yes, you can bet that Ajax gave him a mandate when he signed for them. His previous teams were counter attacking teams while his Ajax team was a heavy possession team.So this is what he wants to play, and Ajax forced him into a better compromise?
My guess is that his ideal is a mix of what he did before Ajax and things that he learned with Ajax, the issue being that he doesn't know how to amalgamate them.
