Cabaye is class when fit, but Joe Ledley bring something to the team that is hard to explain. Quick feet, can shoot, simple passes (but has the occasional strange mistake in him like the Defoe one and an other at Goodison) - still very comfortable with him and MacArthur in the middle. They just seem very compatible. Whatever, it is a nice problem to have - add Chungy in here and we have a very strong midfield to choose from.
