Robbie Williams has blasted Oasis for doing a "13-year lap of honour".
The 'Bodies' singer has criticised the 'Live Forever' hitmakers - who split this summer after relations between bandmates and brothers Liam and Noel Gallagher became unmanageable - for only releasing one good single in over a decade.
He said: "To be honest, I know there's history between us and this isn't very complimentary, but they've been doing a lap of honour for the past 13 years. There's been the occasional gem here and there. 'The Importance of Being Idle', and well, that's about it."
The 35-year-old singer has also admitted he thinks his former friends are too "stubborn" to ever reunite.
He is quoted by Britain's The Sun newspaper as saying: "Originally I thought they'd inevitably get back together because they are the band. But reading between the lines, they're both really stubborn so I don't think they will."
Robbie became friends with the brothers in 1995 after he quit boy band Take That.
However, their friendship turned sour years later when Noel labelled him a "fat dancer from Take That".
The 'Angels' star hit back, branding the guitarist a "mean-spirited nasty little dwarf" and reportedly sent a funeral wreath to the band following the release of their 2000 LP 'Standing on the Shoulder of Giants' with a note reading: "R.I.P. Heard your latest album ."
Meanwhile, Robbie - who has just released his highly-anticipated comeback single following a three-year-break - has shocked fans by pulling out of the MTV Europe Music Awards (EMAs).
It has been reported the former Take That star is unhappy with the way his return to the charts has been handled.
MTV have blamed his withdrawal from the music award show on "scheduling conflicts", while Robbie's team have refused to comment.
