Swindon’s player-of-the-season travelled with the squad to St George’s Park for the summer training camp. But the 21-year-old only appeared once for Pompey and failed to impress boss Danny Cowley. He has since rejoined Swindon and has made 25 appearances for the League Two side this season. Photo: Pete Norton
