Spain’s London 2012 Olympic football star Juan Mata will be expected to lead the charge as Premier League side Chelsea attempt to see off League One Brentford at the second time of asking.

The playmaker has made just nine FA Cup appearances during his time at Stamford Bridge. In those games, he has had a hand in no fewer than 10 goals, scoring four and claiming an assist on another six.

After a 2-2 draw at Underhill, the two teams meet in a fourth round replay this Sunday as most of the other teams still in the competition play their fifth round ties.

It was a shock that the Bees managed a draw in the last encounter to force this replay, so Chelsea are big favourites at home.

Bookmakers Bwin – – have the reigning European champions as 1/7 on favourites to win the match. By contrast, you can get odds of 17/1 that Brentford will be able to pull off an incredible giantkilling act against Rafa Benitez’s side.

Misfiring striker Fernando Torres’ only goal in his last 12 Chelsea appearances came in the original clash with Brentford, prompting more than one cruel suggestion that League One might be his current level. Nonetheless, if you fancy Torres to continue to bully a smaller team, you can get odds of 3/1 on him opening the scoring at the weekend.

Given his aforementioned excellent FA Cup form to date, perhaps Torres’ compatriot Mata is a safer bet. You will get slightly more generous odds of 5/1 on the midfielder scoring first.

On the Brentford side, keep an eye out for Marcello Trotta. The young Italian, currently on-loan at the Bees from Chelsea’s Premier League rivals Fulham, has looked sharp in his brief stint at Underhill. He’s scored three goals in his four games for the Bees, including one against Chelsea in the previous meeting.

You can back him at 18/1 to score the first goal, or 9/2 to score anytime.
