According to L'Equipe, Barcelona are closely tracking Liverpool midfielder Mohamed Sissoko.
Sissoko's future at Liverpool is shrouded in doubt following the signings of Javier Mascherano and Gremio starlet Lucas.
Barcelona could be keen on the Mali international, who is unlikely to have any qualms about returning to La Liga.
Meanwhile, Liverpool have reportedly joined the list of clubs interested in Lyon's French winger Florent Malouda.
Arsenal and Chelsea have both previously shown a desire to sign Malouda, but Juventus and The Reds now head the chase.
Malouda has a contract until 2011 at Lyon so Rafa Benitez is likely to have to pay in the region of €20million (£13.5million) to land his man.
I have said on other threads that Malouda would be a great buy. His class. Fantastic LW. However £13.5 mil wouldnt get him. Lyon are no mugs.
