The Daily Mail says Cavani is unsure whether a summer move to Old Trafford represents a forward step in his career.
Playing Champions League football was a key factor for Cavani when he moved from Napoli to Paris Saint-Germain last summer.
PSG will look to recoup the majority of the £55million they spent on Cavani last summer. Likewise, the player will demand a minimum of £6.7m-per-season, after tax, in wages should he decide to leave France this summer.
