NO, but sure would consider Džeko plus cash for Vidal.
The issue that concerns me with getting Vidal in though would be tactical; who misses out for him to play? There's no way he'd come to sit on the bench, even theoretically, but I doubt Yaya or Dinho would be keen on that either. Add to that the fact that we're supposedly getting Fernando in the summer and I think there are other areas we'd be better off worrying about IMO.
And of course, that's not even trying to fit in Milner, Navas, Silva, Nasri or Jovetic or even (snort) Rodwell or Garcia or any of the promising kids like Lopes or Huws. Different types of players, sure, but you can only have 11 on the pitch at once.
