Rush believes Torres will not skip out on Anfield for another club, unless finance and a lack of say in the top end of the transfer market takes it's toll.
He told the Daily Mail: "He'll keep getting better and grow in confidence. When I was 21 in the first team, I wasn't as good a player as I was at 25. Experience helps. He's only 23 years old and I reckon playing in the World Cup this summer will make him even better.
"When he comes back, we might see the best of him then. I don't think he'll leave if Liverpool don't make the Champions League. I think he wants to be a red through and through, like Gerrard. He likes the atmosphere at Liverpool and the fans are giving him that. The only possible reason for him leaving would be the finances.
"The games over Christmas are massive. If you don't win games like the Wolves one, it's not good enough. It makes all the other games even harder. You've got to be looking at three points."
