Dundee United manager Jackie McNamara has taken a group of four players on trial this summer.
The Terrors will run the rule over Kudus Oyenuga, Calum Butcher, Graham Carey and Nadir Ciftci as they look to strengthen their squad.
20-year old striker Oyenuga played for Conference South club Hayes & Yeading United last season after coming through the Tottenham youth academy.
Likewise is 22-year old defender Butcher who kicked off his career with Spurs and also moved onto Hayes after a spell with Danish first division side FC Hjorring.
Joining the aforementioned pair is former Portsmouth, Kayserispor and NAC Breda winger Ciftci and former Celtic and St Mirren midfielder Carey.
