Chelsea fans! - Would you keep a player if he was unhappy!?

I couldn't help but think about what it would be like for us Chelsea fans if we had players who were unhappy and wanted to move away from the club. I am not just talking about any players but people like John Terry & Frank Lampard.

Notice I am not referring to Didier Drogba as we have had to deal with his "quotes" in the papers for five close seasons running up till this past close season where he stated he felt happy at Chelsea for once!.

The reason I am asking the question is because of this article featured in THE SUN about the Arse Captain Cesc Fabregas. I won't go into full details of the whole article but the last part of it amazed me and I myself can't help but think he still wishes he was at the Nou Camp and not the Emirates so god only knows what the Arsenal fans are thinking reading this. He said:

"There were difficult moments. In the end, when I spoke to Wenger he told me no — he was very emphatic, that the transfer was impossible. I'm satisfied for all parties. It wasn't to be and that's that, though in my head I keep thinking it could have been a good opportunity."

Imagine that was one of our boys!. So after reading that it is leading me to ask you all:

Would you keep an unhappy player who's heart is elsewhere no matter how big a player he is for your club?

Let me know your thoughts!
