Liverpool boss Kenny Dalglish was in France on Friday to see Toulouse lose at home to Montpellier.
Also spotted in the stands was Arsenal scout Gilles Grimandi.
Toulouse midfielders Moussa Sissoko and Etienne Capoue, along with Montpellier striker Olivier Giroud, have all been linked with Premier League clubs this season.
Sissoko revealed recently: "I had contacts with English clubs, notably Liverpool, but I preferred to commit myself to Toulouse, the club where I have been educated, to get more experience."
