Messi's existing deal at Camp Nou is due to expire in June 2021, and there has been speculation surrounding the Argentina international's future in recent weeks.
The 33-year-old was hugely critical of Barca in the aftermath of their 2-1 loss to Osasuna on July 16, and a recent report claimed that Inter were confident of pulling off a deal for the attacker next summer.
However, according to Gazzetta dello Sport, Inter are working on a potential move behind the scenes and are prepared to offer the South American a four-year contract worth €260m (£235m).
Messi has again been in excellent form for his Spanish club this season, scoring 30 times and providing 26 assists in 42 appearances in all competitions. body check tags ::
