TRYING to second guess Jose Mourinho is an impossible task.

With an embarrassment of riches in the Stamford Bridge dressing room, good luck in predicting the Chelsea starting line-up that will emerge against City.

Mourinho made eight changes for the previous round when his side beat Watford 3-0, all the goals coming after the break through Willian, Loic Remy and Kurt Zouma.

If the third round is anything to go by, Remy played wide on the left with Didier Drogba as the lone striker.

Not that he lacked for attacking support, with Remy and World Cup winner Andre Schurrle pushing forward alongside him.

Drogba, who will captain the team if John Terry is rested, has a particular affinity with the FA Cup.

He is the only player to have scored in four finals – against Manchester United, Everton, Portsmouth and Liverpool – and Chelsea won them all in the space of six years. "This is Drogba's stadium," said keeper Petr Cech after the last of those triumphs in 2012.

The Ivorian's first win eight years ago was also the only time that Mourinho has lifted the famous trophy. Guus Hiddink was in charge in 2009, Carlo Ancelotti the following year and Roberto Di Matteo on the fourth occasion.

Cech is likely to return in goal after Thibaut Courtois came back from injury to star against Liverpool in the Capital One Cup in midweek.

With the second leg of that semi-final at Stamford Bridge on Tuesday, Mourinho is likely to give some of his biggest hitters a break. But look out for a potentially star-studded bench just in case things do not go according to plan for the Special One.

But do not expect Chelsea, who are still chasing glory on all four fronts, to dismiss the Bantams lightly. Mourinho has rammed home the message that every competition matters.

Cech, who has made 489 appearances in his 11 seasons at Stamford Bridge, said: "Every trophy is important and I never compare.

"Obviously if you win the Champions League, there is a difference. But over the course of one particular season, you want to win every game and winning every trophy is the aim."
