2) Cristiano Ronaldo (Manchester United, 2009)
A truly world class great, Cristiano Ronaldo’s exit from Manchester United was a massive blow as Real Madrid swooped for him in 2009. The Portuguese international helped the Red Devils to the title in his final season, as well as to the final of the Champions League, and although United could not repeat this feat the following year, they only dropped to second place in the Premier League, taking it to the final day of the season against Chelsea, whilst also securing silverware with a win in the League Cup.
