Millwall have got off to a great start and their summer business has already started to pay off.

Neil Harris has shown what an astute manager he is as the Lions are off to an unbeaten start, whilst his shrewd additions are already proving how effective they could be this season.

Many fans would have been understandably concerned at losing their two main strikers in Lee Gregory and Steve Morison, and with both first-team goalkeepers also departing.

Despite that, Millwall remain much the same; their home form is as strong as ever, the players brought in look to have improved the team, and they are starting to look up the table instead of what is behind them.

One player who has stood out more than most is Matt Smith. The target man joined from Championship rivals QPR, and he looks ready-made for this Millwall side.

He has started two of the three games in which he has featured, although it was his introduction which earned Millwall a point at The Hawthorns as he bundled home the equaliser.

In typical Smith fashion he has caused all manner of problems from set-pieces and has proved difficult to compete with in the air. He struck Millwall's winner at the weekend and could be on course to record his highest ever goal tally for a season, which currently stands at 12 league goals.

Millwall have often relied on the physical presence of Lee Gregory and Steve Morison over the last few years, but with Smith in the side their absence is negligible.

To demonstrate the impact he has made, in the 156 minutes of Championship football he has played so far he has won a remarkable 85 duels, and 41 aerial duels.

That shows how much he encapsulates the battling spirit that is a key feature of this Millwall side and a major reason why they have been successful under Harris. Smith's attitude has been questioned in the past but he already belongs to this Millwall side and seems to have found a like-minded football person in Harris.

Gregory was ideally suited to The Lions not just because of his goals, but because of his work rate and the 100% effort he put into every game, and so far Smith has replicated that.

He is Millwall's main goal threat but also understands that he is the first point of defence, and his average of 3.25 recoveries in the opposition half is evidence of how hungry and determined he is to win the ball back for his side.

Smith's goals will mostly come from set-pieces this season, and certainly from crosses into the box. That means if he continues to gain an average of two free-kicks per game he will create opportunities for him or his teammates to score, although due to his height and physicality he is just as often penalised and adjudged to have fouled his marker.

There are still aspects of his game that Smith needs to work on, too. He has never been technically gifted and comes to life when the ball is in the air rather than on the ground, so if he can improve his finishing and ability on the ball then he could be the complete Millwall forward.

His average of six forward passes per game could do with improvement but it is important to consider the context in which he was playing. Against West Brom, Millwall were chasing the game and his job was solely to get on the end of long balls and crosses, whilst in the match against Sheffield Wednesday his side had only 31% possession.

Overall, it has been a fantastic start for the 28-year-old and he will be determined to maintain his scoring run against former club Fulham on Wednesday.
