Forgot about the swap deal offered with Silva. They're just not interested and thats pretty much how it is.
Same with Chelsea, they could have done a swap with Azpilucuetta and Alonso, it was mooted, but never occured. So that tells me that de Jong himself was never interested in Chelsea, so that was a non starter.
Not sure why people find it hard to believe that he really would want to come to United and be the main man and have everything built around him.
PSG, Chelsea, City... they're just not interested or they know that when stuff is sorted, he's United bound regardless
