Maybe because Gaitan would be okay trading europa league finals and being knocked out in the group stages of the champions league, for a season without european football?
Cuadrado and Sanchez seem to have multiple options of clubs that could win the tournament, the only thing that could possibly convince them to come here instead is us offering them a lot more cold hard cash
I'm not saying we shouldnt out-wage european giants to secure a Sanchez or Cuadrado, if we could pull it off it could be a huge boost for us. But it'd be hard to get them if we won the league let alone not being in europe, so realistically its asking for too much
