Millwall Under 23s' boss Kevin Nugent bemoaned his side's lack of ruthlessness after Monday's derby victory, but also praised a "really good performance" against Charlton Athletic.
Goals from Reuben Duncan and George Alexander handed the young Lions a 2-0 win over their near neighbours in the Professional Development League, a win that takes them into the second promotion spot - albeit with Coventry City being one place and one point behind, with three games in hand.
"It was a really good performance today," Nugent told millwallfc.co.uk. "It's always a tough game against Charlton, they've got some good players.
"We played a slightly different system today, which, without too much preparation, the lads adapted to really well throughout the game. We were the deserved winners. The only downside for me is that we weren't clinical enough.
"We had a lot of set-plays and good deliveries - I'm happy that's my only moan, though. We could've had a couple more goals and in all honesty, it could've been seven or eight."
Frank Fielding played his second 90 minutes as part of his recovery from an injury sustained on the opening day against Preston North End, whilst the Under 18 quartet of Jay Barton, Nana Boateng, Hayden Muller and Jacob Munting made up the substitutes' bench - and Nugent had praise for them all.
"Frank is a great lad and a real pro. He helps the team from the goalkeeping position. We were short on numbers for the 23s, but the lads have done well in the 18s, in the Youth Cup and they're also flying high in the League, so it was good to have them on board."
Next up for Millwall is a trip to Queens Park Rangers on 27th January.
