Meanwhile Southgate is facing a full-back reshuffle with Liverpool manager Jurgen Klopp also confirming on Friday that Trent Alexander-Arnold is out for a month with a hamstring injury and Chelsea manager Thomas Tuchel casting doubt on whether Reece James will join up following his own recent injury issues.
Included will be behind-the-scenes access to the climax of this season for their title-chasing under-18s and also their under-23s who have qualified for the end of season play-offs, with promotion to the Premier League 2 Division 2 play-offs.
Palace will take on the Addicks at Selhurst Park at 19:00 BST as they prepare for the 2021/22 Premier League season, which kicks-off just over a fortnight later on 14th August.
Palace were interested in Mayoral in the summer, but Roma manager Jose Mourinho wanted him to remain at the club. However, the signing of Tammy Abraham has meant that Mayoral has not featured all too often this season.
The 45-year-old, who began his coaching career with New York City FC in Major League Soccer, takes charge for the first time in the Premier League, having made his name as one of the game’s greatest midfielders during a decade-long spell with the Gunners.
