Diego Costa has said that he is unsure if he deserves unconditional love from Chelsea supporters.

The Spain forward scored his second goal of the season on Wednesday as his side opened their Champions League campaign with a 4-0 win over Maccabi Tel Aviv.

However, Costa admits that his recent form has not been good enough.

"I don't know if I deserve the fantastic support that they give me every game," Costa is quoted as saying by The Guardian.

"I often don't do anything and the fans still chant my name. They treat me very well and I'm very grateful for that. As I said, I don't know how much I deserve it.

"It's very important for the players to feel the warmth and support of the fans. That can often win you games. If you see the fans are there supporting you, it's like having an extra player."
