I think he got worse as the second half wore on. He defiantely looked more settled in the second half when moving to the right hand side of the pairing, but in all honesty he and Kaboul just weren't working as a pairing at all.
Kaboul is finished as a player capable of playing for a team which aspires to the upper reaches of the league. Post his injuries he no longer has the spring to dominate in teh air and is slow/labourious on the turn
