Lefevere just paid hard cash to learn what it means what most Spanish 'GT talents' are.
But really, from 'De Omloop' on almost every pro race on Belgian soil is broadcasted live on national TV. Apart from actually winning the TDF, winning 'de Ronde' is the highest you can get. Roubaix is a good third. There are a lot of guys who can potentially win those races. There are maybe 2 or 3 who can win the TDF. Lefevere understands this. He wanted Contador and I'm sure he would have build a hell of a team around him, but he couldn't het him and unless Schlecklet gets into a fistfight with Riis Lefevere is not going to be on the market for a GC contender anymore. You can say a lot about Lefevere (and please do) but he knows how to pick his fights.
Lotto on the other hand put a lot of money in an unlikely TDF victory. They got next to nothing the last years. Gilbert can't cover up everything on his own there.
