Chelsea boss Roberto Di Matteo is set to ring the changes and alter the formation of his side after their poor run of form continued with a 2-1 defeat at West Brom.
The Blues have taken only two points from their last four league games to leave Di Matteo ruing another bleak November for Chelsea. Peter Odemwingie scored the West Brom winner after Eden Hazard had cancelled out Shane Long's opening goal.
Di Matteo said: "This season we are playing a little bit different but we might have to go back (to a previous formation) to be able to win games, and make sure first and foremost we don't concede. Maybe it is the time where we might have to change a little bit in terms of our selection and the way we play."
Chelsea dominated for long periods but Di Matteo was unhappy with the defending for both of the home side's goals and is set to shake his side up. He said: "It is a ground we find difficult, last season when we lost here, and now this season again. We know they are very good at home.
"But giving away goals like we did today makes if difficult to win the game. You have to score three goals to win then and our defending was very poor today.
"We didn't concede many chances but, the ones we did, we had to do better."
West Brom boss Steve Clarke is not allowing himself to get too excited after his side climbed into fourth position.
He said: "I'm delighted, a great three points, good attacking play, two fantastic goals, and dogged determined defensive play towards the end.
"Can we think of the Champions League? I don't look that far ahead, I look from game to game.
"It is a great time to be at the club and if the supporters want to dream a bit, they can. But within the camp, we will keep our feet on the ground."
