Oldham Athletic have signed midfielder Callum Whelan on a two-year deal following his release by Championship side Watford.

The 21-year-old began his career with Manchester United but did not make a senior appearance for the Red Devils.

He went on to join Watford in 2019 but only played two first-teams games for the Hornets, both in the FA Cup.

"I'm really looking forward to giving my all for this club as there is a lot of quality in the team," he said.
