Regarded as a strong attacking-midfielder, Seb Boothe made the move to the West Ham United Academy as an U12s player and scored a number of important goals for the U16s in the 2021/22 season. 

Having made his U18s debut as a substitute in the Premier League Cup, Boothe signed his Scholarship deal with the Hammers in June 2022.

Boothe made two appearances in all competitions for the U18s during the 2022/23 as the young Hammers won the U18 Premier League South and the FA Youth Cup.
