Valdes is set to leave the Nou Camp at the end of the season, and the Catalan giants are searching the globe for his replacement, with Lloris emerging as a target.
Much will depend on whether Tottenham qualify for the Champions League, but if they miss out, boss Tim Sherwood could be facing a huge battle to keep hold.
The Frenchman has been a big hit at White Hart Lane and Barcelona are not the only club showing an interest in him.
Big-spending Paris Saint-Germain could offer him the chance to return home, while high-flying Atletico Madrid are also in the running to take him to La Liga.
However, the chance to play for Barca will be a huge pull for Lloris, and Spurs will be hoping they switch their attentions elsewhere for Valdes' replacement.
