I read somwhere, that it was because of Panathinaikos, but I suppose it could have been some rumours. If Zagumny has some personal problems - it is completely different case.
Yeah, I've just read an interview with Castellani. It seems that they aren't really problems, just his wife is pregnant and he's got additional responsibilities. I read an interview with Zagumny earlier and he said that there are some personal matters, but he didn't want to elaborate on that.
