Beyond the great illusion of seeing their team in the highest category of Spanish football for another year, the Rayo Vallecano fans will surely go to bed today with even more desire for the start of the next season. This Monday it was known that the Madrid club's first rival in preseason will be none other than the almighty Manchester United.

The meeting will be held at Old Trafford on July 31 at 5:00 p.m., Spanish peninsular time, and will serve as preparation for their respective seasons in the Premier League and LaLiga Santander.

It will not be the coming-out of Erik Ten Hag's team, because the day before the English team will face Atlético de Madrid in Oslo.

But for the fans of the 'red devils' it will be the opportunity to see the new project for the first time in the 'Teatro de los Sueños'.

“We are delighted to be able to offer people the opportunity to witness Ten Hag's debut at Old Trafford. Fans who purchase their tickets for this match will also be helping a good cause as the club will donate 10 per cent of the proceeds to the Manchester United Foundation," said Collette Roche, director of operations for the triple European champion.
