If you're just starting your second season, see if Valdes is still available on a free. If not, there are still a large number of options. Go for Neuer, if you can prise him away from Bayern, Joe Hart is a good goalkeeper, Petr Cech still has a couple years in him, and David De Gea is obviously a good prospect. Normally I wouldn't go for these players, I'd go for the likes of Ter Stegan and Bernd Leno and Thibaut Courtois, but if money is no issue and you can get anyone you like, those are the proven top class goalkeepers.
