According to Sportsmail, West Ham United have become the first English Premier League side to train at their home stadium as manager David Moyes tries to replicate behind-closed-doors conditions ahead of Project Restart.
Other top-flight sides are said to be preparing to emulate the concept in the coming days with league action expected to return on June 17.
The Hammers played a match that lasted around 60 minutes between the first-team squad in their full kit on Saturday at the London Stadium, and Moyes is hoping it will adequately prepare them for the tough task ahead.
