Jose Mourinho is not happy about releasing three of his Tottenham players, including recently fit-again Gareth Bale, to work under Arsenal coach Albert Stuivenberg at Wales.
Stuivenberg, an assistant to Mikel Arteta at Arsenal, has been on the coaching staff of Ryan Giggs at Wales since 2018.
He will have greater responsibility for three games this month, starting with a friendly against the USA in Swansea on Thursday because Giggs is absent after his arrest and allegations of assault.
Rob Page and Stuivenberg will be in charge of a squad that includes Spurs trio Bale, Ben Davies and Joe Rodon, and Mourinho believe this represents a conflict of interests.
