Speaking at the premiere of a new film about the band - the younger brother says they should never have split up.
Liam Gallagher has said he is ready for an Oasis reunion - but will not go "cap in hand" to brother Noel to make it happen.
The band's ex-frontman said that the band should never have split up in 2009 and that his "bags are packed" if the opportunity arises to get the group together again.
"If it happens tomorrow, I'm ready, my bags are packed. If it happens in a year, I'm still ready, if it happens in 10 years, I'm still ready.
ready, my bags are packed. If it happens in a year, I'm still ready, if it happens in 10 years, I'm still ready.
"But there'll be no cap in the hand and no banjo, you know what I mean? A little f****** skinny, stringy dog outside his house going 'please sir, I need a f****** band, mate.
"If it happens, it happens, if it doesn't, it f****** doesn't, we move on."
Speaking at the launch of Supersonic, a new documentary film about the band, Liam, 44, could not resist a dig at his older brother - who did not attend the screening.
"He won't be here - he's in one of his really, really, really, big houses, probably eating tofu, while having a f****** face peel, ain't that right, man of the people?"
Wearing his trademark parka jacket, Liam admitted to missing his older brother "without a doubt".
But he also accused him of "ruining" his Oasis career.
"He just wanted to do this thing, there is a lot of angst there. For someone to ruin my Oasis career to further his own, we have got to get past that a little bit."
Supersonic - made by the team behind award-winning documentaries Amy and Senna - charts the formation and rise of Oasis.
Following the group through the early '90s, the film includes commentary from family and unseen archive material.
