Jack Colback was slow to shut down Jonjo Shelvey as he played a well-timed through-ball into Bafetimbi Gomis which led to Swansea' opening goal. His overall performance was very average and he was out-muscled by Jack Cork and Gylfi Sigurdsson too often. I still feel that the former Sunderland midfielder needs to do more going forward as his overall service to the attacking players is extremely limited.
