Simon Grayson started his professional football career at Leeds but failed to establish himself in the first-team squad. He later returned to the club as a manager, where he helped them win promotion to the second-tier in the 2009/10 season, finishing as runners-up to Norwich City after a dramatic final day win against Bristol Rovers
Although Simon Grayson began his professional football career at Leeds, he was unable to make a name for himself in the starting lineup. Later, he rejoined the team as manager, and he assisted them in winning promotion to the second division in the 2009–10 campaign. They came in second to Norwich City following a thrilling victory over Bristol Rovers on the final day of the season.Summerville, a Rotterdam native, signed his first professional deal with Feyenoord, a local team and national powerhouse in the Netherlands. He never played in a competitive first team for Feyenoord; instead, he went on loan to Dordrecht, a Dutch second-division team, where he scored five goals in the league in just eighteen games.
The next season, he was loaned to Eredivisie club ADO Den Haag, where he scored the club’s youngest goals ever in the top division with a tap-in against Vitesse.
Dutch news outlet Voetbal International reported that Summerville had rejected a contract offer from Feyenoord following his successful loan deal at ADO Den Haag. He later signed for Leeds on a three-year deal.
The talented young attacker has been capped at U16, U17, U18, U19, and U21 levels by the Netherlands and has scored goals for each team.
It remains to be seen if Summerville will continue his rapid rise at Elland Road or elsewhere.
