Drogba left Stamford Bridge after almost single handedly winning them the Champions League last season.

"When you think of the season he's just had, I must say it is a big boost for us that Drogba is leaving Chelsea," Ferguson said in The People.

"He scored that fantastic goal in the final with two minutes to go and his goalscoring record in the big games, in big finals, is incredible.

"As far as I was concerned, he won the Champions League for Chelsea."
