PSG rounded off a successful season with a 4-0 victory over Montpellier last night, although Cavani took no part.
Cavani has endured mixed fortunes since his switch to Ligue 1 - despite scoring 16 goals in 30 league appearances, the Uruguayan forward has previously hinted he was unhappy having to play second fiddle to Zlatan Ibrahimovic - prompting speculation that Manchester United could make a move for his services.
However speaking on the pitch after last night's game the striker pledged his future to PSG.
'[Will I be at PSG] next season? For sure!" he is quoted as saying during PSG's title celebrations.
The news will come as a setback for Manchester United who are looking to get their transfer business done early this summer.
The Red Devils are already trying to lure Luke Shaw to Old Trafford having reportedly already made a £27 million bid - although that has been turned down by Southampton.
They've also been linked with a swoop for Arsenal full-back Bacary Sagna who is available on a free transfer this summer.
Despite all the activity however Manchester United are yet to confirm who their new manager will be - although it is expected that Louis van Gaal will take up the reigns at Old Trafford after the World Cup, with an announcement coming next week.
