Tyrese Briscoe and Sean O'Brien found the net as Millwall's Under 23s were 2-1 winners at Beckenham Town in a pre-season friendly on Tuesday night.
Briscoe opened the scoring after just 22 seconds, whilst O'Brien's second-half strike proved to be the winning goal after the hosts equalised from the penalty spot.
Naming three trialists in his starting XI, Kevin Nugent opted to field Joe Wright in goal and the usual suspects such as captain Dan Moss, Junior Tiensia and O'Brien - the latter pair also playing for the first-team in the behind-closed-doors pre-season friendly against Fulham earlier in the day - and straight from the kick-off, The Lions were in front.
After O'Brien received the ball in the midfield, a pass over the top saw a cross go into the box, with Briscoe finished to open the scoring with just 22 seconds on the clock.
The home side recovered well from their early shock and set about pinning Millwall into their own half, and their reward came shortly before the half-hour mark as the referee pointed to the spot after a foul inside the area - Wright was sent the wrong way from the resulting spot-kick.
Briscoe, O'Brien and Trialist A all had close-range efforts blocked as The Lions looked to go back in front moments after, and with the score level at half-time, the beginning of the second-half was all about O'Brien as the attacker had numerous attempts to register on the scoresheet.
Firstly, he sent a shot just wide of the post on 48 minutes, before a free-kick hit the frame of the goal nine minutes later. An O'Brien free-kick was nodded wide by Arthur Penney on the hour-mark, with a further effort - this time a dipping 25-yarder - going just over the crossbar.
With 72 minutes on the clock, however, O'Brien finally got his deserved reward, tapping home after a driving run and cross from Tiensia.
There were opportunities for The Lions to extend their lead after that, but the final whistle blew on another pre-season success for Nugent's side shortly after.
Next up for the Under 23s is a pre-season friendly at Eastbourne Borough next Tuesday.
