Former Manchester United goalkeeping coach Emilio Alvarez says David de Gea was "disloyal" to him after renewing his Old Trafford contract.
Alvarez had been brought to the club by Jose Mourinho in 2016 in order to work with De Gea, but he stayed on under Ole Gunnar Solskjaer after the dismissal of the Portuguese in December 2018.
After months of negotiations, De Gea eventually signed a new deal at United in September last year, with Alvarez departing the club shortly afterwards.
The coach says he had been asked to stay on by the club, but wanted to leave as he felt De Gea hadn't showed loyalty to him when signing the deal and he now didn't want to work with him any more.
"After almost three years with lots of work and meetings with United to renew him and to make him the best-paid player in the world, I learned that he had renewed behind my back," Alvarez told AS.
"Honestly, it felt like a lack of loyalty. During negotiations, he also had a falling out with the person who had carried out all the talks in order for him to be paid what he was paid.
"And at the last minute, someone else meddled. I insisted that I didn’t like that because it seemed disloyal.
"I asked David why he didn’t say anything to me and he said that he was told not to say anything to anybody. This had an impact on me.
"The way I understand my profession is that you can’t help someone develop if you do not have total confidence with them and that’s why I decided to leave United.
"It’s not true that Manchester United relieved me of my duties. In fact, once De Gea renewed, United put an offer on the table for me.
"It was me who asked to meet with the club so I could tell them I wanted to leave the club. It was at this meeting the asked me to renew.
"I told them I was going but not because I wanted to leave United. I wanted to stop coaching De Gea."
