Tel explained to the media while on France U21 international duty how Frank had let him know the disappointing news.
"Quite simply, with respect. He called me, he simply told me his choice and then you could see the list appear on the networks," said the attacker, as quoted by Le Telegramme.
"It's clear that when you're not on a list, it definitely hurts, but I'm someone who stays pretty positive, no matter the situation, because I think I've worked a lot on the mental aspect, so today it's definitely a disappointment, I would have liked to be there. But the coach's choice is the coach's choice, we can only respect it and we're going to work to come back in the best possible way."
Tel was asked whether it had made him want to leave Spurs or simply do better to take his own form of revenge on the decision to exclude him from the Champions League squad.
"No matter, even if I was on the list, I would have had this desire, to be revengeful, to be able to be effective this season, to be able to start my season in the Premier League, because now, it's a first long season that begins because last year it was in the form of a six-month loan," he said.
"A desire elsewhere? I am under contract with Tottenham [until 2031], so I am a Tottenham player and I will do my best to be able to play quite simply."
Tel admits that his initial half-season loan spell with Spurs could have gone better as he struggled to hit the ground running in an injury-ravaged Tottenham side without a striker.
