Antoine Griezmann admits he is open to a move to Manchester United but has revealed one thing which may get in the way of his transfer. It appears the Atletico Madrid star is somewhat concerned about the climate in the north of England. The forward revealed all in his new autobiography, Behind the smile: The life of the little Prince. Speaking of a potential move, Griezmann wrote in his book: 'I haven't made that decision. It all depends on various factors. 'Manchester United is a possibility.' Jose Mourinho missed out on the forward last summer after Atletico had a transfer ban imposed on them, meaning they couldn't bring in a replacement for their talisman.
