Crewe have clinched the signing of defender Patrick Ada from non-league side Histon.
The 24-year-old centre-back has been with Histon since 2007 and has made 85 appearances for the club.
Gudjon Thordarson has been impressed with his progress and has brought him in on a two-year deal for an undisclosed fee.
Thordarson will be relieved to have bolstered his squad after admitting last week that prospective recruits were being put off by the offer of League Two football.
The Railwaymen suffered relegation from the third tier of English football after a disappointing campaign which culminated with three straight defeats.
