Derby County have signed West Ham goalkeeper Joseph Anang on a season-long loan.
He helped the Saints reach the Europa Conference League third qualifying round during his spell at the League of Ireland Premier Division side.
He is the third goalkeeper, alongside Joe Wildsmith and Scott Loach, signed by the rebuilding Rams this summer.
Anang, who is yet to make a first-team appearance for the Hammers, spent time on loan at Stevenage in League Two last season before going on to join St Patrick's.
He made 30 appearances and kept 12 clean sheet during his time with the Saints.
