The Blues defender admitted mistakes were made in last weekend’s loss to Everton but insists that the squad aim to make amends in fifth-round clash at home to Birmingham
The west London club are winless in four Premier League games following the 2-0 reversal against Everton last Saturday.
The defender has now admitted that the Blues’ form has been lacklustre of late and he hopes team meetings held this week will benefit players.
“We had a couple of very good things come out of last weekend,” the 27-year-old told Chelsea’s official website.
“We sorted out a lot of problems and we have worked very hard in training as well.
“We are doing our best. It is a very hard period for us but we have to believe, we have to have trust in each other on the pitch and believe that better things will happen for us.
“It is very important to have communication between the manager and the players. For the players, it gives us confidence and we know what we're doing right and wrong. They [the meetings] can help."
The club host Championship promotion contenders Birmingham City in the fifth-round of the FA Cup this weekend and the Serbian international believes the side must be victorious.
“That is why it is good that we have had a good rest and worked hard in training as well. We are ready for Birmingham and the rest of the season,” he added.
“We play at home and we have to win the game. I think this is one of the most important moments for us where we can change the rest of the season.”
