The former England international, who will become a free agent next summer when his contract with Stoke City expires, has long been linked with a switch to Loftus Road.
Discussing that speculation, Merson believes that securing the services of the 33-year-old would boost QPR's chances of avoiding relegation from the Premier League.
"For me, QPR need him. I'm a big fan of Peter Crouch, he's a good player. It's a nice small pitch at QPR. They need to make Loftus Road a fortress, because if they don't, they will be relegated. I don't see them winning too many away games. If QPR can get Crouch, he will tick all the boxes," the former Arsenal and England midfielder told Sky Sports News.
