Robert Pires has been pictured training with Arsenal suggesting another shock return for an Arsenal legend is on the cards, reports The Independent.
The French winger has not played competitive football since being released by Aston Villa in 2011, but has returned to London Colney to shore up his fitness.
A return to Arsenal would not be the first time Wenger has turned to a former star to improve the squad.
Sol Campbell, Thierry Henry Jen Lehmann and most recently Mathieu Flamini have all left the club only to be brought back on short term contracts. The exception being Flamini, who was given a two year deal after impressing in training.
Although a return is unlikely, Wenger will undoubtedly like having the Frenchman around the club, having recently stated that Thomas Eisfeld reminds him of Pires.
"He is a Pires type", Wenger said of Eisfeld when speaking to Arsenal's official website.
"He appears to be in the box without being noisy and appearing suddenly. When he is there, he finishes well.
Eisfeld, 20, opened his Arsenal account of Wednesday against West Brom and Pires could prove to be the perfect mentor.
Pires left Arsenal in 2006 for Villarreal after his contract expired. His last appearance for the club was an 18 minute cameo in the Champions League final against Barcelona.
Arsene Wenger substituted the French winger for Manuel Almunia after Jen Lehmann was sent off - an act Pires later revealed decided his fate.
The winger made 284 appearances for Arsenal from 2000 to 2006, winning two Premier League titles, three FA Cups and scoring 84 goals.
