The 21-year-old, who played under Shrimps boss Sammy McIlroy at Edgeley Park, has agreed a deal subject to passing a medical at Christie Park.

Allen made 50 league appearances for the Hatters but was not offered a new contract after spending six months on loan at Royal Antwerp last season.

McIlroy made his move for Allen, who can also play at right-back, after Fraser McLachlan broke his leg.
