Chelsea needed almost an hour to break the deadlock against Brentford in their FA Cup fourth round replay but once Juan Mata had found the net, the result was never in doubt.
The Spaniard fired home from 20 yards to break the League One side’s resistance and Oscar doubled Chelsea’s advantage with a delightful backheel.
Frank Lampard added a third with his 199th goal for the club and John Terry completed the scoring with a back-post header as Chelsea set up a fifth round meeting at Middlesbrough on Wednesday week.
