Last season wasn't so bad. At least, as said, he worked hard, and improved as the season was advancing.
I'd keep him, we'll need him when Asamoah has to leave to the African Nations Cup. Just in case we don't sign someone else.
Or we could just play 4-3-3 with Chiellini on the LB...
He has the same problem as Litch, he's not a LWB/RWB, he is a LB, and doesn't has the hability and the knowledge to attack, though some of his crosses are better than Asamoah's ones.
And defensively I'd say he just does his work, but nothing remarkable.
