The Gunners are facing a goalkeeper exodus at the Emirates and need to source reinforcements.
Poland international Wojciech Szczesny is widely expected to leave the club permanently.
The 27-year-old has spent the last two seasons at Roma in Serie A.
Their league rivals Juventus are keen to secure his services.
Meanwhile David Ospina has also been linked with a move away from north London.
The Colombian shot stopper has played second fiddle to Petr Cech.
He's regularly deployed in cup competitions but could leave in search of regular first-team action.
French news outlet Le 10 Sport reckon Lafont could be a potential arrival.
Lafont is just 18-years-old but has already made 60 appearances for Toulouse.
It's suggested he could be a long-term replacement for 35-year-old Cech.
Le 10 Sport say Lafont isn't the only French goalkeeper being scouted, though.
They've also had spies tracking St-Etienne ace Stephane Ruffier.
Ruffier, 30, is a more experienced campaigner.
He's played over 300 Ligue 1 games and has been capped three times for France.
