Kevin Nugent was left less than impressed with Millwall Under 23s' showing in Tuesday afternoon's 1-0 defeat to Charlton Athletic at The Den.
The defending champions suffered a first Professional Development League defeat of the season courtesy of Josh Davison's fourth-minute goal, and in speaking to millwallfc.co.uk, the manager stated how his outfield players should be indebited to Ryan Sandford, who made numerous saves.
"I'm really disappointed," he said. "We started off really slowly, had a bit of a period in the first-half where we were in the game, but in the second-half we never really got going.
"Ryan Sandford made some very good saves and kept the game alive until the end, and we still could've got something out of it, but overall, I'm very disappointed."
The Lions had Reuben Duncan sent off on 65 minutes, potentially changing Nugent's thinking behind substitutions as Millwall chased the game.
"[The red card] didn't make much difference. It maybe changed my thinking a little bit, but we had chances to get something from the game after that. That's football - it was a local derby with tackles flying in."
One player The Lions were without for the visit of The Addicks was Harry Ransom, who moved on loan to Dover Athletic earlier this week until 29th December.
"It's good experience for Harry, and he got off to a good start with the winner on Saturday as well. We brought him in from a Conference South club, and it's a good standard there too with Andy Hessenthaler as manager."
