Goals from teenage strikers Tobi Alabi and Connor Wilkinson secured a hard fought 2-1 win for Millwall against Gillingham in a behind-closed-doors friendly at Calmont Road on Tuesday afternoon.
The Lions went ahead with just three minutes on the clock when Alabi played a neat one-two with Dammi Shitta and then calmly slotted home the opening goal from close range.
Unfortunately the young goalscorer was then forced off injured after 18 minutes to be replaced by Wilkinson, and just three minutes later Jordan Stewart also left the field injured with Dylan Richards taking his place.
It was sub Wilkinson who struck the second goal for Millwall on 27 minutes with a lovely finish into the far corner from 20 yards that gave Gills keeper Paolo Gazzaniga no chance.
At this stage The Lions were coasting against a very young Gills team featuring featuring manager Andy Hessenthaler's son Jakob.
The visitors' only real chance of the opening half came courtesy of a diving header from Nathan Nyfli, but Steve Mildenhall was equal to the effort with a comfortable save in the home goal.
Josh McQuoid had a good opportunity to put Millwall 3-0 ahead just before the break, but sent his header narrowly wide of the post.
After half-time Gillingham changed their shape and came into the game much more with The Lions finding it difficult to regain the momentum of the opening first 45 minutes.
Gills sub Bradley Dack should really have scored three minutes after the restart, but contrived to sidefoot the ball straight into the hands of grateful keeper Mildenhall from eight yards.
At the other end McQuoid miscontrolled having been played clean through and keeper Gazzaniga was able to block at the expense of a corner.
Gills reduced the deficit shortly after when Darren Purse upended Ashley Miller in the penalty area and Jack Evans slammed the resulting spot-kick past Mildenhall.
The visitors - and Dack in particular - had a hat-trick of opportunities to haul themselves level in a frantic final 10 minutes.
Dack's first effort was hit straight at Mildenhall, his second on 83 minutes saw the keeper parry at full stretch onto the post and around for a corner from which Dack then headed wide at the far post from close range.
Speaking shortly after the final whistle Lions coach Richard Shaw Shaw said: "I was pleased with the performance, although the team fell away a bit in the second half when we struggled to regain the initiative of the first.
Overall I can't complain about the result."
