Liverpool new boy Ramon Calliste has vowed to make sure Manchester Utd regret releasing him.
Calliste was speaking after inspiring Wales Under 21's to a 3-0 victory over Azerbaijan.
Calliste stated: "I was shattered by what happened at Manchester United. It was a real blow when I was released, a shock to the system.
"But when you get offered a chance like I have had, straight out of the blue, you take it. I grabbed it with both hands, it's a wonderful opportunity for me. Frankie Mac (Liverpool scout) rang me and told me he has seen me playing as a 13-year-old and hadn't forgotten me. I can't thank him enough. Now I have no intention of letting Liverpool down.
"I went on trial at first and it went well and I recall scoring on my debut in the reserves. That has got me a one-year contract and I aim to give it everything, it's a chance in a lifetime after what happened to me at United.
"I am absolutely determined not to let Liverpool down, they have taken a chance on me and I aim to repay them for that.
"Just to be training at the same place as the first team is tremendous for all of us. And I have found myself being one of the older lads, we've got 17-year-olds there who are outstanding and we have all been brought into the club at the same time."
Wales under 21 boss Flynn said of Calliste: "He is still only 19 and he has another two years with us. He's been at Manchester United and now at Liverpool, where he has raw talent that they are clearly working on.
"It is a great opportunity there for him and he is now producing good team play rather than just individual talent.
"He has pace, control and movement and the team play heis getting into his game is why he has improved."
