The 'Candy' hitmaker has reignited his feud with the rockers by claiming they'll have no choice but come back together for the sake of their reputation because he's convinced the next album they release as solo artists will end up being a flop.
Speaking to The Sun newspaper's Bizarre, the 44-year-old singer said: ''I think there will be [a reunion]. Liam Gallagher has just come back and he's done pretty well. He had a platinum record with his solo album and I think that's what everybody was waiting for. I think the next time he releases an album it won't do as well.
''Noel's album didn't do too good either. I think it sold like 70,000 copies or something, which for Noel isn't great. If they're anything like me, which I think they are, they will want to be doing the most successful thing they can do, and the most successful thing they can do is a reunion. I think they'll both need to do it.''
Robbie and the Gallagher brothers have been at loggerheads since 2000 when he challenged Liam to a fight at the Brit Awards and then a decade later told his brother Noel to kiss his ''perfectly formed backside'' while he was on stage.
But Robbie wasn't the only one dishing out insults as Noel famously referred to him as the ''fat dancer from Take That'' while Liam branded him a ''fat f*****g idiot'' in 2013.
Meanwhile, Liam - who famously fell out with his older brother, leading to the demise of their group in 2009 - took to social media recently to insist he ''forgives'' Noel for what has happened in the past and admit he would love reform Oasis.
He said: ''Earth to noel listen up rkid I hear your doing gigs where people can't drink alcohol now that's the BeZarist thing you've done yet I forgive you now let's get the BIG O back together and stop f***ing about the drinks are on me LG x (sic)''
