British Olympic sprint champ Darren Campbell has confirmed he's been working with Chelsea striker Andriy Shevchenko.

Shevchenko was back on the scoresheet yesterday in Chelsea's 6-0 humbling of Manchester City and Campbell revealed: "I've been working with Andriy about two months now. The club got in contact with me and asked if I would work with him and I said it would be a pleasure to help one of the greatest goalsorers.

"While Mourinho was at the club he was a little bit funny about anybody from outside working with the players. But it was something Shevchenko wanted to happen, so for the first couple of sessions I had to do it at his house on his tennis court.

"Now that Mourinho is gone I'm able to do it at the club. Shevchenko was paying for it, that's how serious he is about sharpening up and trying to improve himself.

"So for all the Chelsea fans who are on his back, I can say he really is trying to improve himself and play well for the club.

"Over the last few months it's definitely worked, he's been scoring for Ukraine and for Chelsea in the Champions League. We've been working on his 10m and 30m pace. He's improved by a few tenths which is what the club wanted."
