#1 To win the Balon d'Or
Griezmann has come close twice to lifting the prestigious Balon d'Or but missed out on both occasions. The 28-year old French international is at the peak of his career and will want to lift the individual honour at least once.
He will never be able to do it at Barcelona, especially when Messi is still at the club. Players leave Barcelona to get out of Messi's shadow and get recognition and Griezmann must be aware of the fact. But Manchester United can give him that opportunity. The club is in transition under Ole Gunnar Solskjaer and will be ready to compete for major honours in a year or two.
Griezmann will be the star of the team and will be under the limelight all the time at Manchester United. If the Frenchman can help the Red Devils get back to the glory days, his chances of lifting the Balon d'Or will be significantly high.
