Meireles faces his old club at Stamford Bridge.
He said: "Liverpool are very good this season but in the last few weeks have suffered some disappointing results. They always seem to raise their levels against the bigger clubs and that's why it won't be easy to beat them.
"Luis Suarez is on a good run and has just scored four goals for Uruguay against Chile.
"He is dangerous for any rival and will be highly motivated. He is the key man but I've passed on the secret of how to stop him to our defenders!"
