HITC Sport understands Cardiff City are set to win the race for the Rochdale winger, ahead of the likes of Wigan.
Nathaniel Mendez-Laing of Rochdale applauds fans at the end of the game
Mendez-Laing is available on a free transfer this summer after running down his contract at Rochdale.
The 25-year-old impressed for Rochdale this season, making 49 appearances in all competitions, scoring 10 goals as Dale just missed out on making the League One play-offs.
Nathaniel Mendez-Laing of Rochdale has a shot at goal
A number of clubs, including Wigan have expressed an interest in the former Wolverhampton Wanderers and Peterborough United man, but Cardiff are poised to secure his signature.
The chance to move to the Championship was too good for Mendez-Laing ahead of the other offers he received and he is in line to become Cardiff's first signing of the summer.
Cardiff boss Neil Warnock is looking to reshape his squad at the Cardiff City Stadium as he prepares for his first full season in charge of the club after taking over last October.
Warnock guided Cardiff away from trouble at the wrong end of the table to finish in 12th spot, but he is planning to build a squad capable of challenging for promotion next season.
