Conor hits a brace as Lions beat Swans
The impressive Alabi broke down the left flank and found Wilkinson who turned smartly before slotting into the corner of the Swansea net.
Unable to muster much of a fightback, the visitors found themselves with a mountain to climb when Wilkinson added a third on 69 minutes.
Not to be deterred, The Lions roared on and were back in front minutes later. A corner fell to Goodman who, after a neat turn, struck a half-volley into the top corner; leaving Swans keeper Davies clutching thin air.
The second-half began in much the same way but there was to be an equaliser against the run of play. Swansea were awarded a penalty after Jake Goodman was penalised for a push in the box, and James Loveridge made no mistake from the spot to even the score at 1-1.
The visitors could only hold on for so long and Millwall were rewarded for their dominance with 25 minutes on the clock. O'Brien was first to a second ball and his knockdown was squeezed over the line by Wilkinson.
The one-way traffic continued as Batt and Tobi Alabi saw efforts go over, with Swansea's only attack ending in a rasping 25-yard drive which failed to test Steve Mildenhall.
Tam Mkandawire, Therry Racon and Shaun Batt all started the game and helped the hosts to make all the early running. Batt went close early on when he was fed a pass from Aiden O'Brien before he returned the favour, only for Oliver Davies in the Swansea net to save well.
Goals from Conor Wilkinson (2) and Jake Goodman were enough to ensure a comfortable 3-1 victory for The Lions U21 Development Squad against Swansea on a wet afternoon at The Den. Team: Mildenhall, Newman, Mkandawire, Goodman, Richards, Sammoutis, Racon, Alabi, Wilkinson (Penny, 83'), Batt, O'Brien. Subs not used: Bartlett, Oriogun, De Havilland, Twum.
