Blackburn Rovers boss Steve Kean has hailed the impact of Yakubu Aiyegbeni this season.

The Nigerian was again on the scoresheet in victory at Manchester United.

"It is fairly obvious," said Kean.

"When you see the amount of goals he has got now, we are desperate to keep him fit.

"We look after him. He is in as good a physical condition as he has been in his career and we manage him during the week.

"There are times when we need to give him an extra recovery day because of the amount of mileage he is doing.

"We don't ask him to run to the channels. We just ask him to play the width of the box.

"We know if we can give him good service, he can get himself some goals."
