He has to play either deeper in midfield where he has space to knock 30 yard passes, or stick him upfront and ask him not to do anything defensive.
Really though the answer is bench him. Alli is better as a 10, Vardy and Kane are better as a 2, and playing him wide is completely pointless. I would probably try him in midfield over Milner in last nights formation, but he would probably struggle there anyway.
Either way the 4-1-2-1-2 looks a poor formation, it relys so heavily on fullbacks, but we don't seem to push them high up enough to fully make it effective.
