#1: Jack Powell is ready for more first-team action
Jack Powell's performance against Southampton has given Ian Holloway a decision to make.
Before yesterday's Capital One Cup tie, Powell was being considered for a loan move to the lower leagues to get him playing competitive first-team football.
But the 20-year-old didn't look out of place against a Premier League side and Holloway may now re-think his plans for the midfielder.
Powell's distribution was neat and tidy, and he looked composed on the ball.
Speaking during the summer, the youngster revealed his admiration for Shaun Williams' style of play and there were certainly comparisons to be drawn between the two players last night.
He was always willing to receive the ball and showed quick feet to navigate tight spaces in the centre of the park.
Powell lost possession on the edge of his own area moments before Southampton took the lead from a corner – but David Forde quickly apologised for giving him a dangerous pass.
Holloway revealed after the game that Powell spent pre-season bulking up in the gym and he certainly held his own against top-flight opposition.
Judging by last night's game, the Lions have a real talent on their hands – and one who could be ready for Championship football this season.
#2: Chaplow shows his potential against former club
This was Richard Chaplow's first competitive appearance since March – and it was arguably his best performance for Millwall since he joined the club last summer.
Chaplow's 2013-14 campaign was ended prematurely by an Achilles problem and his injury frustration continued when he tweaked a hamstring in the final friendly of pre-season.
But last night he looked fit, hungry and sharp. He gave Millwall an attacking impetus going forward with several driving runs through the heart of midfield.
The Lions have lacked penetration in central areas but Chaplow showed last night that he is capable of troubling defences with his direct approach and trickery.
The 29-year-old did plenty of tracking back too, winning the ball inside his own half and generally showing a determination to fight for every 50-50 ball.
Under Steve Lomas, the former Saints favourite struggled to make an impact when played out on the wing and his Den career has been hampered since then by injury concerns.
But Chaplow has proved that, when fit, he's a classy player – and one that Ian Holloway could certainly use this season.
#3: Williams' transition to centre back was seamless
Shaun Williams' performances have been one of the biggest pluses of Millwall's season so far.
Williams' style of play matches Holloway's philosophy perfectly and the Dubliner will probably be the first name on the teamsheet for Saturday's clash with Blackpool.
But having established himself as a midfield mainstay, Williams last night filled in at centre back, the position he played for over two years during his time at MK Dons.
And the 27-year-old was just impressive in the back four as he has been in the engine room.
Williams was still able to affect the game with his distribution from a deeper position and his simple passes ensured Millwall kept the ball under pressure.
His importance to the squad was also underlined by the fact that Holloway handed him the captaincy in Alan Dunne's absence.
It seems that wherever Williams plays, he finds a way of making himself stand out.
#4: David Forde mixes up his distribution
Millwall's goalkeeper has been asked by Holloway to mix up his distribution.
Forde is under instruction to alternate long punts up field with quick throws and short passes to a defender. And last night we saw both the pros and cons of this approach.
The 34-year-old's fast thinking created a golden chance for Magaye Gueye with the score at 0-0.
Spotting the forward in space, Forde lumped the ball 60 yards into his path, giving him a clear run on goal. Gueye wasted the opening but Forde's pass to him was phenomenal.
The Ireland star has already created one goal this season – against Fulham – by finding Lee Martin with a long ball over the top, and the same trick is bound to work again.
But the Lions are still adjusting to the short pass out from the back.
Forde was one step ahead of Jack Powell when he played the ball to his feet on the edge of Millwall's area. Southampton were able to nip in, win possession back and force a corner.
From the corner, Jack Cork headed home the opening goal.
Holloway said after the game: "Fordey's distribution was absolutely fantastic.
"People are shouting at me, 'what are you doing?!', but you've got to get used to it. He almost produced the best pass of the game [to Gueye] after we drew them onto us.
"There's a balance between rolling it out and playing it, so we're going to stick to that. We almost caught out a Premier League team with one pass.
"We wouldn't have created that chance if we'd kicked it out on the floor every time."
