My guess mate, is the Kiev owner and Everton are a few million apart (or terms of payment) and to show he is sticking to his evaluation he has played him - basically showing he isn't afraid to lose the deal etc, Everton will stump up what they want guarantee it
Also think it is the only reason they have left him on in this game is to effectively put pressure on us
....hope you're right but I if we want him we should just make it happen.
