The Poland international is on the way to the Serie A side on loan.
The Poland international has fallen down Arsene Wenger’s pecking order after a number of blunders last term cost the Gunners points.
The French coach dropped the 25-year-old mid-campaign last season and replaced him between the sticks with David Ospina, who was a more consistent option.
With the summer signing of Petr Cech from rivals Chelsea, the likelihood of Szczesny getting first-team football at the Emirates Stadium has reduced further.
Wenger confirmed that the loan switch to Roma was nearing, but the goalkeeper has taken to Instagram to reaffirm the point.
Speaking in Italian, Szczesny confessed that he was on his way to the Italian capital to pen a deal with Rudi Garcia’s men.
“Good evening Giallorossi! I am very happy, because I am going to Roma tomorrow. I'll see you soon,” he said.
Wenger has claimed that the controversial custodian still has a future at the North London club, with this switch to Roma an ideal short-term fix to offer him regular action at the top level.
With the Stadio Olimpico outfit playing in the Champions League also, there is every chance that Szczesny could end up facing his parent club in Europe next season.
