With each passing week the need for Manchester United to make January reinforcements becomes clearer. Jose Mourinho wants a No10 after the failure of Henrikh Mkhitaryan to establish himself - even if Juan Mata has looked positive over Christmas. But perhaps the area most in need of address is up front. Romelu Lukaku is feeling the strain of carrying the load. He looks exhausted after being asked to lead the line by himself all season. Mourinho gambled on Zlatan Ibrahimovic being able to take that pressure off the Belgian once he regained fitness. But it feels like the Swede will never be able to regain the form that made him such a hit last season.
