"It’s hard for Ballack at Chelsea because this club is special," Drogba told The Sun on Thursday.

"At Chelsea, we depend on our individuals. So, maybe Chelsea is not the right club for Ballack."

German midfielder Ballack moved to Chelsea in the summer of 2006 on a free transfer after ending his adventure with Bayern Munich.

However, he struggled for form in his first season at Stamford Bridge before sustaining a serious ankle injury in April and was sidelined since then.

Ballack was even omitted from Chelsea's Champions League squad as speculation linked him with a move away from the club.

Ivorian striker Drogba, who made headlines recently for expressing remorse at joining Chelsea, believes Ballack should have joined either Manchester United or Arsenal.

"I’m convinced he would have had a much easier time at Manchester United or Arsenal because they benefit from their well-balanced team — he would have been a better fit there."
