Jesse Debrah was the match-winner as Millwall's Under 23s defeated Bolton Wanderers 1-0 in the Professional Development League on Friday afternoon.
The centre-back notched in the 71st minute to give Kevin Nugent's side three points in their pursuit of a top two place in the Southern Section.
Frank Fielding played 60 minutes on his return from injury, whilst Harvey Bradbury completed the full 90 as he makes his way back to full fitness after a period out.
"It was a frustrating game," Nugent told millwallfc.co.uk. "We had so many chances but were unable to convert them. However, we got the one we needed."
Next up for Millwall's Under 23s is a home game - at Calmont Road - against Colchester United on Tuesday 7th January 2020.
