Millwall's youngsters followed up their convincing 2-0 win over Cardiff City earlier in the week with another excellent display to beat Brighton & Hove Albion.
After an even opening few minutes, it was The Lions who almost made bagged the first goal of the game as Zak Bryon fired narrowly over the crossbar having been played in by Nico Thongvivat.
Five minutes later, however, Millwall did indeed make the breakthrough when Keaton Wood side-footed his effort past Brighton keeper Christian Walton following a corner from Callum Thompson.
The Lions doubled their lead soon after when a cross, again from from Thompson, was nodded back across the goal by Alfie Pavey and there was defender Callum Webb to plant the ball into the net despite the best efforts of Walton.
At the other end, Lions stopper Tom Beadle had to be alert on the half-hour mark to palm away a snap shot from Emil Asmunden, this coming when the home side looked well in control.
Two minutes before the break, and with The Lions cruising to what seemed to be a comfortable lead at the interval, Brighton halved the deficit with a speculative effort from distance by Charlie Harris; a strike which came totally against the run of play.
Ten minutes into the second period, Brighton were given an opportunity to draw level when they were awarded a penalty for a handball incident in the Lions box. Fortunately for Millwall, however, Wiltshire’s spot-kick crashed against the upright and away.
In the 68th minute, a cross into the box by substitute Hammed Laval was just too high for fellow substitute Jamie Philpot to get a clear header on goal before the latter almost played in John Prince Rylah, a replacement for the injured Thongvivat.
The Lions were once again turning the screw, and eventually that pressure paid off in the 78th minute when a super run and cross by Laval found Philpot who smartly directed his low drive into the bottom corner to make it 3-1.
There was controversy late on in proceedings when Ben Thompson’s close range effort looked to have crossed the visitors’ goal-line.
As the home players turned to celebrate a fourth goal, Brighton played the ball out of the goal mouth and, to the surprise of everyone, including the Brighton players, play resumed with the goal not given.
