Willian has attributed his poor form this season to the injury he suffered while on international duty with Brazil in the Copa America during the summer.
The Brazilian has made several substitute appearances for the Blues this season but he has failed to have an impact in games with the Brazilian criticised for his performance against Leicester City.
Willian has admitted he needed some time in training and he’s 100 percent fit now and raring to go, should he be called upon.
“I had an injury when I was at Copa America and I needed some time in training to recover, but now I am 100 per cent,” Willian told Sky Sports.
“I have to continue to train hard and when I have time to play I have to play well.”
Chelsea have won just one of our opening four games this season but Willian insists Chelsea possess the squad to challenge for titles this season.
“I think Chelsea can win some titles this season,” Willian added. “I know it will be hard this season to win titles, as usual, it is always hard.
“It is difficult when you lose players like David Luiz, Eden Hazard, but we have some quality young players here who can improve a lot and in the future become one of the best players in the league. I think we have a great team.
“But Chelsea is a big club and this shirt is heavy. When Chelsea go into a competition we go to win.
“It does not matter the players, it does not matter the coach, every year we want to win something, and I think this year we can do it again.”
