I actually think Moura was effective and tried different things the whole time he was on the pitch.Son, Lucas and Dele were always going to be ineffective against a team playing 10 at the back. 2 of them rely heavily on space and getting in behind while Dele relies on the other attacking players to create holes by pulling defenders out of the position in which he pops up. If we'd have had Messi playing up top or on the wing last night he wouldn't have been able to do any more. Of course Eriksen was going to be the most likely to create given he was deeper and Brighton gave him all the time he wanted.
