Millwall opened up their pre-season campaign with a 5-0 win over Dartford in the Kent sunshine on Saturday afternoon.
Jed Wallace opened the scoring early on with a free-kick before doubling his tally and The Lions' advantage shortly after the half-hour mark.
A quick flurry of goals then saw firstly Aiden O'Brien and then Mahlon Romeo find the net, before Steve Morison tapped home a rebound from Wallace's missed penalty just before the break.
Millwall boss Neil Harris opted to field a separate side in each half, with new signing Murray Wallace taking his place in the second-half team.
Just two minutes in, Millwall took the lead. O'Brien's run down the left-hand side set up a free-kick around 20 yards out, which Wallace curled home with style to open the scoring.
Dartford attempted to threaten shortly after but failed to trouble Jordan Archer, whilst at the other end Fred Onyedinma looked to break into the opposition penalty area to no avail.
On 25 minutes The Darts looked to level, but captain Morison was well placed to clear Ronnie Vint's header off the line. Igahore's follow-up effort flashed wide.
Three minutes later Onyedinma collected the ball and charged towards goal, but a superb covering challenge from Roast prevented The Lions from doubling their lead.
They did just that, however, on 31 minutes. Onyedinma once more broke away and flashed a ball across the box - Wallace's initial strike was saved by Deren Ibrahim, but the winger followed up to slot home his second of the afternoon.
On 33 minutes, Millwall raced into a 3-0 lead. Shaun Williams' free-kick was deftly headed on by O'Brien, with the Irishman finding the net.
It took just two more minutes for Millwall to add a fourth. Harry Donovan's through-ball sent Romeo away, with the right-back sending an unstoppable left-footed shot into the far corner.
Two minutes from the break a fifth was added, but in unfortunate circumstances for Darts 'keeper Ibrahim. Wallace, on a hat-trick, placed a spot-kick down and fired a shot towards goal, but the stopper pulled off a smart save. The winger followed his shot up, only for Ibrahim to save again, however, at the third attempt, Morison was on hand to pass into an empty net.
The Lions' second-half team began as the first one ended, but after an exchange of passes between Ryan Tunnicliffe and Tom Elliott, the former's shot was blocked away for a corner-kick.
James Brown's ball over the top was controlled by Elliott who slotted under the legs of Ibrahim for what looked like Millwall's sixth, but the linesman ruled the strike out for handball.
Shane Ferguson's cross just after the hour-mark found Lee Gregory, but the striker's flicked header looped over the crossbar. Elliott then headed over from Mason Saunders-Henry's cross as The Lions seeked more goals.
Just under 10 minutes from time Saunders-Henry set Gregory away, but the striker's shot was saved by Funnell.
Given the temperature and England's looming World Cup Quarter-Final with Sweden, the tempo and atmosphere at Princes Park dropped somewhat as the game neared its conclusion, but The Lions will certainly be happy with their opening game of pre-season.
