The Primera Liga outfit are set to find themselves without a first-choice goalkeeper once David de Gea completes his proposed move to Manchester United.
The youngster arrived in England on Monday to undergo a medical and is close to putting the finishing touches to a big-money transfer.
Speculation has already begun to circulate regarding who may be drafted in by Atletico as his replacement.
Liverpool number one Reina has been touted as a possible candidate, after spending the last six years away from his homeland.
The Reds ace has given short shrift to the rumours, though, by insisting that he remains fully committed to the Anfield cause.
He told La Gaceta: "I know Atletico are looking for a goalkeeper, but I won't be changing colours.
"I have a five-year contract and I'm happy at Liverpool."
Reina will come into direct competition with De Gea next season and he believes the 20-year-old will be a resounding success at Old Trafford.
He said: "I very much welcome this news because David is a great keeper.
"When it becomes official he is going to start working to prove in the Premier League what a good goalkeeper he is."
