ACADEMY boss Scott Fitzgerald believes there is "more to come" from Millwall's youngsters after their 2-0 victory at Bromley on Saturday.
The Lions have entered a development team into an U21 league for the first time this season and Fitzgerald believes regular competitive football will aid the development of the club's rising stars.
The youth campaign kicks-off with a match against Brentford on Saturday, with details of the full fixture list to be published soon.
Only three first-team players – Alan Dunne, John Marquis and Shaun Batt – featured in the team at Hayes Lane, with the likes of Jack Sammoutis and Jake Goodman putting in impressive displays against a much older Bromley XI.
"It was good that the senior lads got the match minutes, which was pre-planned," Fitzgerald told the club's official site.
"With a week to go before our season starts, this was a much-needed solid work-out.
"Our younger lads coped well with Bromley, and it was nice for the development squad to keep their first clean sheet of pre-season.
"It was the intention in our planning that all the pre-season games played by the development squad would be against first teams, rather than youth teams.
"This has been a very good experience for them, but I know that there is more to come from them too."
Millwall's development squad have been entered into the same league as Swansea, QPR, Cardiff, Colchester, Ipswich, Brentford, Bristol City, Charlton, Brighton and Barnet.
