Unfortunately yes. Last year Carlos Tevez outlined team passion and committment to the cause by either scoring goals or chasing after that ball so much, that defenders would dread it if they saw a small Argentinian bulldog running towards them:
And any press announcement he had, it was full of praise for United. About the players, the manager, and how he would stay at the club for life for the fans. And what happens towards the end of the season? The man develops an ego complex and starts doubting the club when a new contract hadn't been offered straight away. Long story short, a re-extension was offered just when we finished the last game of the season, as promised, but by then Tevez seemed to take it as some personal offense and he and his agent arranged a big money move elsewhere. That place being, just down the road, to our derby rivals, Manchester City:
What's more offensive though is how much shit he talked about United when he joined City. How much the manager paid no respect to him at all. He tried to backtrack before the derby matches this season by saying how he doesn't anticipate why the fans would dislike him so much after the move. Umm, you talk shit about our manager, one of the greatest there's ever been, and you moved to our rivals, even when we offered you the contract extension you solely wanted plus a salary increase! The man scored in both derby matches this season and each time he ran over to the United supporters and cheered in front of us, even when he said he wouldn't. So much for club loyalty. Prick.
Dennis Law was another one who moved from Utd to City but that was different. He was in his glory years and this was a free transfer. But more than that though, on the last game of the 1972-73 season, City played against Utd. Things weren't going well for us at the time and as it turned out, a draw or a loss would have seen us relegated from the First Division. Law scored a goal in that match to make it 1-0 to City but he didn't know a draw would have seen us go down anyway. So he didn't celebrate it, and in fact was so dejected that there was no choice but to substitute him. Legend.
