Why are Real Madrid allowed to close Bernabeu roof?

Real Madrid will close their retractable roof at the Bernabeu for their Champions League match against Manchester City on Wednesday evening.

In order to close the roof for Champions League games, the club need to get approval from Uefa, which was granted by European football’s authorities.

The club see it as a way of creating an intimidating atmosphere for away opponents and also boost the noise of the home crowd.

Uefa have previously allowed the club to close the roof for Champions League matches, including during last season’s quarter-final against Arsenal and in 2024 against tonight’s opponents.

It did not have an effect on Arsenal, with Mikel Arteta’s side winning the second-leg, while Manchester City held Real to a 3-3 draw.

The retractable roof was added to the stadium as part of its renovations in 2024.

The club added a 360 degree scoreboard screen to the ground and also a bigger seating capacity as part of the £1.5bn construction work.

Some have complained about the roof, saying it creates a “greenhouse effect” inside the ground and compared it to be in a sauna.

No Premier League clubs have access to a retractable roof, but the Principality Stadium in Cardiff, which hosted cup finals between 2001 to 2006, does.
