Sudarshan drives data strategy at Newcastle FC

On a match night at St James’ Park, home of English Premier League side Newcastle United, when the stadium hums and sways to every pass, tackle, move and goal by the home team, emotion drives everything. Behind the noise, another game unfolds quietly. This one is built on code, cameras and millions of data points. That invisible game is now central to how the club trains, competes, plans the season and even buys players. And helping to run it is an Indian-origin technologist whose journey spans American classrooms, Silicon Valley, and Europe’s biggest leagues.

Sudarshan Gopaladesikan is Newcastle United’s technical director. Technology at the club supports almost every aspect on and off the field. But Sudarshan’s focus is firmly on the football side. His job is to help players stay fit, help coaches prepare smarter and help the club make better decisions in the transfer market.

Sudarshan was born in Harrisburg, Pennsylvania, to parents from Tamil Nadu. He studied mathematics at Swarthmore College, a leading liberal arts institution. His career began in technology at Microsoft, where he worked on the team that developed Power BI. A project with Real Madrid introduced him to elite football. From there, he moved into club roles with Benfica in Portugal and Atalanta in Italy before joining Newcastle United.

Data, data, data
Sudarshan’s role in Newcastle is heavily dependent on data. And the data flows during a match, and as soon as a match ends. By the following morning, Newcastle would have received detailed digital files from specialist providers. One stream is event data, which logs every ball action, such as passes, shots, tackles and interceptions. A single game can produce three to four thousand such events.

The second stream is tracking data. Stadium camera systems capture the position of every player and the ball around 25 frames per second. Over 90 minutes, that becomes roughly three to four million frames of positional information from just one match. Imagine what this is across an entire season! Analysts clean and transform the data, and process them through cloud systems before turning them into visual reports, key metrics and short, focused video clips. It is presented to coaches as clear insights linked directly to moments from games.

Analysts study how Newcastle functioned in possession. Where did they break defensive lines with passes? Where did they struggle to progress the ball? What happened after they regained possession? Out of possession, they look at where chances were conceded and how well the defensive shape held. Set pieces, now responsible for a significant share of goals in top level football, are examined in detail.

These findings feed directly into training. Training sessions too are filmed from multiple angles, sometimes using drones, and matched against the tactical priorities identified through data. Coaches narrow the message to a handful of key themes players must carry into the next game.

Monitoring physical performance
Technology also plays a vital role in monitoring physical performance. Every player’s locomotion is tracked, says Sudarshan, including total distance covered, maximum speed, acceleration, deceleration and changes of direction. Metrics such as repeated high-intensity efforts show whether a player can sprint again and again over short periods, a crucial quality in modern football.

Off the pitch, fitness is monitored through a mix of testing and medical data – strength assessments of major muscle groups, jump tests to help measure explosive power. Blood markers after matches can indicate stress and recovery levels. Sleep and diet are monitored, sometimes through wearable devices and sometimes through detailed questionnaires, depending on how comfortable players are with certain technologies.

Solving for starting team, substitutions
All of this context shapes one of the most debated aspects of the modern game: starting team and substitutions. To fans, it can be baffling when a player doesn’t start or one who looks lively is taken off. Inside the club, that decision is often backed by data.

During matches, Newcastle monitors players in real-time. These track not just how far a player has run, but how many high intensity actions he has performed and how closely they are clustered. A player might look fine to the eye, but the data can show he has reached a physical load that significantly increases injury risk, especially when recent matches and training sessions are taken into account. The aim also is not only to win that day’s match but to keep key players fit for the weeks and months ahead.

When the transfer window opens, much of the same data underpins recruitment decisions. Newcastle uses event and tracking information to build detailed profiles of potential signings. They look beyond statistics, measuring how players move, create space, defend and cope with physical demands. Recruitment, Sudarshan says, becomes a complex optimisation exercise, balancing performance data, contract details, league strength and financial considerations to find players who best fit Newcastle’s way of playing.
