Conor Gallagher featured for Chelsea U23s in their 3-0 win at Derby County.
Ross Barkley played an hour and Daishawn Redan scored a hat-trick away at Derby County in Premier League 2.
St George's Park was the venue for Chelsea's penultimate away fixture of the season and Joe Edwards had four of England's Under-17 World Cup winners in his matchday squad at the national team's training base.
Gallagher made his first start of the season at this level in midfield, while Marc Guehi debuted in defence.
