Real Madrid will replace the pitch at the Bernabeu for the fifth time this season ahead of their Champions League semifinal with Manchester City, with coach Carlo Ancelotti admitting the surface is "suffering" amid stadium construction work.

The Bernabeu is undergoing an €800 million renovation -- including a roof and retractable pitch -- which began in 2020 and is due to be completed later this year.

The team have continued to play at the stadium as building work goes on, although the quality of the playing surface has deteriorated.

Madrid have already had to replace the grass four times, with a fifth now imminent before the first leg with City on May 9.

"The [construction] works affect that pitch, that's obvious," Ancelotti said on Saturday after Madrid's 2-0 LaLiga win over Celta Vigo. "We've changed the pitch periodically and we'll keep doing that, it's nothing new or surprising.
