Millwall have completed their fourth signing of the summer transfer window, after securing the signing of winger Connor Mahoney from Premier League side Bournemouth.

The 22-year-old has signed a long term contract at The Den after joining for an undisclosed, and will look to help Neil Harris' side pull further away from the Championship relegation zone, having finished just one place above the dotted line season.

Mahoney himself spent last season on loan in the Championship with Birmingham City, and was named the club's Young Player of the Season at the end of the campaign.

So is Mahoney a good signing for the Millwall?

We've put the spotlight on his performances during his time on loan at Birmingham last season to find out.

Looking at Mahoney's stats here in comparison to those of Millwall's squad for last season, it certainly seems that the winger will be capable of making an impact at The Den.

Among Millwall's squad, only three players provided more assists across the course of the season than the four Mahoney provided for his Birmingham teammates, and two of that trio - Lee Gregory and Steve Morison - have since moved onto pastures new.

That leaves defender Jake Cooper, who provided six assists last year, as the only member of the Lions squad to provide more assists than Mahoney, which certainly indicates he will be a welcome addition to the club's attacking ranks.

Delving deeper into the statistics, the reason behind Mahoney's greater number of assists than his new teammates does appear to become clearer.

Amongst last season's Lions' squad, only Shaun Williams, Shane Ferguson and the now departed Ben Marshall averaged more crosses per game than Mahoney's 1.6, while Ferguson and Wallace were the only ones to better Mahoney's average of 1.4 key passes per game, with the central midfield duo each averaging 1.6 per game.

There, however, will be a slight concern about Mahoney's pass success rate of 58.3%, which was bettered by no fewer than 20 members of last season's Lions squad, while ten players averaged more shots per game than the 22-year-old.

That may be the sort of return that most would expect to see from a young, still developing player who is thrust out onto the wings and challenged to deliver as many balls as possible into a heavily guarded penalty area for his teammates to attack.

You feel therefore that that is a risk that Neil Harris' side will be willing to take on the youngster, and the stats do seem to suggest that Mahoney has the ability to make things happen for Millwall going forward. If that is the sort of form that he can replicate following his move to The Den, then it may well be a risk that just about pays off.
