Chelsea goalkeeper Asmir Begovic has claimed that the team is getting better despite their inconsistent form.

The Premier League champions suffered their fifth defeat of the season on Saturday as they went down 2-1 to West Ham United at Upton Park, in a game that saw Nemanja Matic, manager Jose Mourinho and his assistant Silvino Louro all sent off.

Begovic is confident that Chelsea's results will improve if they continue to play they way that they have been.

"This league is very unpredictable so we need to take care of our performances first – I think our performances are getting better so we just need to keep that going," the Bosnian told Chelsea's official website.

"We performed pretty well over the 90 minutes. We got unlucky with the sending-off. I think we had a good goal disallowed as well, so things are just not going for us at the moment.

"I thought we were well in the game, no matter what the situation was, and the tiny little differences didn't go our way. It's coming from all corners at the moment so we have to cope with that. We came back, we showed good character and I think our performance showed we are still positive and trying hard, it's just that little moments are not going our way."

Chelsea face Stoke City in the League Cup on Tuesday.
