Chelsea player ratings from 4-2 win over Swansea City: Diego Costa scarily effective, Eden Hazard terrorises Swans

Centre-back: Gary Cahill – 7/10

Did not make a single tackle all day – because his positioning was spot on.

Midfield: Nemanja Matic – 7/10

Matic was extremely reliable in possession, keeping Chelsea ticking with the metronomic precision of his passing.
