The Chelsea defender Branislav Ivanovic has been one of the regular players for the European champions this season. He has been at the heart of the defence that has to start of the season so well, but has been faltering in recent weeks.

After the 4-2 win over Tottenham in the league, Chelsea are yet to register a single victory in the league, which has meant that they are now in the third position. They have slipped from the point of a four point advantage to the state of a three-point deficit in the league in the matter of a few weeks.

However, the Serbian defender has said that it is extremely vital that Chelsea do not allow the heads to drop and learn from the mistakes that they have committed in the last few weeks. Chelsea will be taking on West Brom in what would be another tough match for the European champions because West Brom have an excellent record at home this season. Chelsea have struggled for a number of occasions over the last few seasons in the months of November, and Ivanovic is keen to end that spell with a victory. He has highlighted the importance of maintaining a clean sheet against West Brom.

"I think in previous years we had almost exactly the same situation as we now have. We need to learn from these experiences, and from the last game against Liverpool we know we need to be more concentrated as a team to win matches. It's important we get the points from this game against West Brom, we tried hard in the other games but we don't have the points and we need to improve this," said the 28-year-old ahead of the West Brom match. He has already scored three Premier league goals this season.
