Canberra Raiders recruitment boss Peter Mulholland has backed calls for the NRL to address the player "meat market" by introducing a transfer window late in the year.

Mulholland described the current climate, where players change clubs at will, as "ridiculous" and believes it can be solved by following soccer's lead.

The Raiders are one of many clubs monitoring developments at Parramatta, who are keen to clear up salary cap space to accommodate Sydney Roosters and NSW Origin centre Michael Jennings.

Canberra have been strongly linked to Eels forward Junior Paulo, but it is understood the club doesn't consider him a realistic chance of leaving Parramatta this year.
