West Ham United boss David Moyes is having his players train in full kit.
The Daily Mail says Hammers players were put through their paces at their home ground on Saturday in a session that included a match between the first-team squad.
Players were even dressed in full kit as the club try to prepare their players for competing behind closed doors in addition to using their Rush Green base.
The session, it is understood, included a mini-training match - a significant development as the Hammers gear up for a return to Premier League action.
The concept of training at home stadiums is set to be used by several top-flight clubs in the coming days as managers try to replicate behind closed doors conditions - but the Hammers have become the first top-flight side to do so.
