The Serie A champions tweeted a video of the Poleintroducing himself to the Turin club’s fans.
It has been reportedthat Arsenal have accepted a £10m bid for 27-year-old Szczesny, who has spent the past two seasons on loan at Roma.
Szczesny played in 38 Serie A games last term and finished with 14 clean sheets, the most in the league.
Though Szczesny was highly regarded by Arsene Wenger he had struggled to convince some at the Emirates who doubted his attitude after an incident in January 2015 when he was fined £20,000 for smoking in the changing room showers after a defeat to Southampton.
David Ospina is also expected to depart this summer, with Turkish side Fenerbahce consistently linked with a move for the Colombian international, paving the way for the highly-regarded Emiliano Martinez to serve as Petr Cech’s back-up next season.
