Lets be honest, he would welcome the move and has clearly been in talks with chinese. So it's not too unfair to say he is seeking the move. I'm sure he would be happy to stay too. But I actually do think both parties, Moyes/Bill & Cahill think a move is best for him at this stage.
And even if he stays, you really see Cahill as good enough to play as our lone striker for the season if anything happened to Jelavic? He stunk the place out last season, with respect to the guy.
Time to put my hidden agenda, on the table here. I really rate Vellios and would love for him to be our first reserve behind Jelavic and stand in should the worse happen. Would hate to see him sent further down the ranks by the likes of Rodallega.
