It's not the first time this has been mentioned by the press though. I do know Harry and Mourinho do have dialogue, but I think in the main it's because Harry is after one of the Madrid players (Diarra).
For what it's worth, Walker seems to be a pretty level headed guy. Although he's not really been around the club on a daily basis for very long, considering much of his time has been away on loan, he does seem very pro-the club. I watched our NextGen home games and at those held at Leyton Orient and Spurs Lodge, he was the only first teamer there to support the youngsters. Plus, he was very patient in posing for photos for fans and signing autographs, which is more than can be said for a couple of the fringe players who were also there.
I saw him play for QPR and was concerned he wasn't all there defensively, and after that he was at Villa and again vulnerably when defending. Since those days, he is such a vastly improved footballer. Every area of his game has come on in leaps and bounds. He is a better player now than in February, and in February he was a better player than he was at Christmas.
We would be stark raving bonkers to even consider selling this player, and if there is any truth in this press report, then Mourinho should be quickly told to go forth and multiply.
