If Frank Lampard leaves Chelsea in the summer, as expected, then victory in the Capital One Cup would at least provide a high note in his final season with the club. It would the midfielder's 11th major trophy with the club.

Having barely seen the ball in the first half, Swansea suddenly take the lead. Branislav Ivanovic loses possession on the edge of the box by miscontrolling a simple pass from the goalkeeper and Swansea capitalise in ruthless fashion with Michu sweeping the ball into the bottom corner Photograph: Adrian Dennis/AFP/Getty Images

What's more, Ba had a goal ruled out for offside in the dying seconds, and the decision seemed rather harsh. Photograph: Carl Recine/Action Images
