Michael Essien insists Chelsea can win all four trophies they're competing for this season.

"They've done a good job and didn't lose a game," he said.

"It didn't surprise me because I know we have the players to do it. The team has done really well, and we have to keep going and continue to win our matches.

"It was very sad to miss out on the African Nations Cup, but you have to forget about the past and look the future. Chelsea have a bright future, and I still have more trophies ahead of me.

"We are still in all four trophies and will work really hard. We have to achieve something and win something this year."
