20 August 2017. It’s Tottenham Hotspur versus Chelsea at the Wembley. Chelsea center-back David Luiz wins a foul close to the Tottenham penalty area around the 23rd minute, and wing-back Marcos Alonso steps up to take the free-kick. He fires it into the top-right corner of the net, and it’s 1-0 to Chelsea. In the 82nd minute, however, Chelsea substitute Michy Batshuayi heads the ball into his own goal and makes it 1-1.
Per 90 minute numbers don’t tell us everything about players.
While per 90s help compare players who’ve played different amounts of minutes, not all players get the same amount of opportunities on the ball. Players who play in bad teams, or even players who play in teams that keep less possession and attack directly, won’t get the ball as much as players in teams in the same league as Barcelona or Bayern Munich.

The Future of Football Analytics
Currently, the biggest issue with football analytics is the lack of positional data for off-ball players. Most of the analytics is done using event based data, in which every pass, tackle and shot is logged. However, event data only contains the ball’s location. This means we as analysts are left guessing on a huge amount of our work. How do we evaluate how difficult as pass is without knowing where the players are on the pitch? How can we quantify the intricacies of good defending against bad defending?
SD Eibar, the smallest club in La Liga which consistently punches above its weight, are currently sitting pretty at 8th in the Spanish La Liga table. The club from a town of 27,000 people in the Basque country, which play at the little Ipurua Stadium, have been putting on some dazzling displays this season under the Basque manager José Luis Mendilibar.
When Barcelona’s 29-year-old midfielder Paulinho scores more goals in the league than a 5-time Ballon d’Or winner, you know there’s something weird going on. Cristiano Ronaldo has only scored 0.4 non-penalty goals per 90 minutes (NPG90) this season. Not ideal for someone who’s famous for wrecking goalscoring records every year.
Let’s start with a statement that looks pretty obvious: Liverpool have an awful defense.
While it may look like their bad defense is down to the incompetence of Liverpool’s individual defenders, it’s largely down to the high-pressing system favored by Jurgen Klopp that’s gone awry this season. When the first line of press is broken (which has happened many times this season), the ball gets into dangerous areas because of the vacant spaces left behind. This leads to tricky situations for the Liverpool backline.

My objective is to focus on the lesser known youth of our beautiful national game, and combined it with a little tactical outlook meant for the football enthusiast, after lots of time and effort I have found a large gap to be exploited in terms of combining the two. This mini-report thus focuses on young manager who mostly work or have worked in Scottish football and their tactical philosophies, deriving what got them here and where they could go.
