The former Reds striker thinks the £10 million summer signing is ready for the Premier League.
The £10 million summer signing was loaned straight back to Lille after signing for the Reds - but Collymore feels he is already good enough to turn out for the Anfield side.
The 43-year-old, who played for Liverpool between 1995-97, says he wasn't convinced by Origi at the World Cup.
But, after seeing him in action during Belgium's 2-0 win over Australia, Collymore now feels the 19-year-old is 'ready.'
Origi. Wasm't convinced at WC but holds it up well, great turning and running, movement in box could be sharper but #LFC fans will enjoy him— Stan Collymore (@StanCollymore) September 4, 2014
Despite his obvious talent, Origi himself has recently vowed to stay patient during his pursuit for a place within the Liverpool side.
"I'll go there with a lot of patience and I know I'm going to learn a lot off the great players, there," he said.
"They welcomed me very, very well. They showed me a little bit about the club, about the history, the philosophy, so it was very interesting. At the end I think it was the right choice."
Indeed, however good the Belgian currently is - or will be - he will have his work cut out when it comes to playing ahead of the likes of Daniel Sturridge, Raheem Sterling and Mario Balotelli.
Is Origi ready to play for Liverpool already?
