Curr I think the point was, We should not pay 20 million for Vargas when it's a risk. We might aswell pay 6 million for Rodriguez and take the risk with him.
Enough, because simply we don't need a Vargas type of players and this guy is one of the most talented on the market that can come out great (That type of players that we keep on missing) while his price would be 5 times lower.
