Man United's secret tactics vs Fulham were exposed by Sky Sports cameras

Manchester United's tactics have been revealed by Sky Sports cameras during their season opener against Fulham.

Erik ten Hag got his first match of the season off to good start as his side defeated Fulham 1-0 at Old Trafford.

New signing Joshua Zirkzee scored on his debut for the club, clinching an 87th minute goal which took home the three points.

And during the Sky Sports broadcast, fans noticed that United's secret tactics were revealed by cameras late in the match.

As Zirkzee made his debut for the club coming on as a substitute in the 59th minute, a diagram telling the forward how to defend corners was revealed.

Overhead cameras showed the Dutchman carefully studying the tablet which showed him which zone to mark whenever the London club were awarded a corner.

A minute later, Zirkzee and teammate Alejandro Garnacho replaced Mason Mount and Amad Diallo in the match.

And it was the two substitutes that combined for the goal nearly 30 minutes later as a cross from Garnacho found the former Bologna striker who calmly placed the ball in the back of the net.

Speaking after the game about his debut, Zirkzee said: "To win here on my debut, and grab a goal, it couldn’t be better. I’m very blessed that I could experience it in my first game. It’s an amazing feeling.

"I feel very warm here, it’s a great squad. We want to achieve something great. I’m taking it in, day by day. [Ten Hag told] just bring energy and help the team as much as possible. Just that.”

The 23-year-old joined Manchester United on July 15 from Serie A side Bologna for a reported fee of £36.5m.

Zirkzee signed a five-year contract with the club, supposedly earning a surprisingly low wage of £56,000 per week.

Upon joining the club, the youngster said: "I know how exciting the future is going to be here and I cannot wait to play my part in achieving success for Manchester United.

“I am a player who has always dedicated everything to winning; I’m ready for this next challenge, to go to another level in my career and win more trophies.”
