New interview with Zuraw from Gazeta Krakowska (local Krakow newspaper - usually they have the best sources in Wisla):

Generally - Zuraw is in Krakow and he takes it easy for a couple of days. He said that this is one of the most important decissions of his life and he wants to think about it for 3-4 days and talk it over with his relatives. He also said that he was happy with Celtic's offer and now it is for the clubs to talk to each other. One of the problems seems not to be the price for Zuraw but whether Celtic will pay it all at once (Wisla of course wants this) or whether they will pay in several installments (Celtic wants to cut a deal here).
Zurawski said that he will not say publically where he wants to go the most and will wait for the teams and Wisla to go forward with negotations. Trabzonspor has not given up yet and has upped the price. As Zurawski said - Wisla now may use the opportunity to negotiate a better deal since they have now two committed sides.
So basically Zurawski now waits for Wisla's green light. He also said that he definietly wants to try his luck in a strong club in the West (not sure if he means it literally - or he just means it outside of Poland - coz. Trabzo isn't exactly west of Krakow - but maybe that's an indication he really wants to play for Celtic).
I hope that - if he leaves - that he goes to Celtic. I love Zurawski and I always liked Celtic. I hope this will be a good match. And if he doesn't go to Glasgow I hope he will stay with us period - Wisla is already talking to a striker so they look like they already made the decission to let him go - which is only fair to the player - he made over 100 goals for us since he came. 120 goals in the Polish leauge in total and he is scoring well for the national team too. He is a goal-machine, but it is time for him to take it up a level.
