Watford are expected to confirm the return of defender Adrian Mariappa on a free transfer.

Mariappa started his career as a trainee at the club and went on to make more than 200 appearances for the Hornets.

The defender moved to Reading in 2012 before signing for Crystal Palace 12 months later. But he left Selhurst Park last month after his three-year contract ended.

Watford have been teasing supporters with a video and it is believed Mariappa will be announced as returning for his second spell at Vicarage Road
