Crawley Town have signed former Watford defender David Sesay on a free transfer as well as ex-Colchester United midfielder Tarryn Allarakhia.
Sesay, 19, was released by the Hornets earlier this summer and has agreed a two-year deal with the Reds.
The youngster failed to make a senior appearance for the Premier League club.
Meanwhile Allarakhia, 20, signs a two-year deal with the League Two club following his release by Colchester United at the end of last season.
Crawley head coach Harry Kewell told the club website: "I worked with David extensively when I was at Watford and know what his potential is."
