Carlo Ancelotti is fascinated by the impending battle between Cristiano Ronaldo and Gareth Bale when Portugal take on Wales in their Euro 2016 semi-final on Wednesday.
The Bayern Munich coach spent two years at Real Madrid and was there when Bale joined Ronaldo at the Santiago Bernabeu for a world-record fee, seeing the two face off many times in training.
And the prospect of seeing the two born competitors face off on a football pitch has Ancelotti intrigued to see how the battle between the two stars and their countries will pan out.
"They all want to come out on top even when the only thing at stake is to be able to walk into the training-ground canteen as the winner.
"So when it comes to the game in Lyon, just think what it will mean to these two lads to do it for their countries."
Ancelotti said he saw how much playing for their national teams meant for both players and even recalled talking to Bale about Wales' chances at Euro 2016 before he left Madrid at the end of the 2014-15 season.
"Gareth always told me that Euro 2016 was a big tournament for Wales," the Italian continued.
"That if they could qualify then who knows what could happen?"
Ancelotti said Portugal were lucky to have not just a talented player in Ronaldo, but a fierce leader as well - qualities which the Italian felt the attacker showed during his country's penalty shoot-out win against Poland.
"I saw the penalty shoot-outs between Portugal and Poland and then Germany and Italy. You could see how Cristiano took the lead by scoring the first penalty," he wrote.
Ancelotti said outside of the star duo, Portugal had the better team on paper but said Wales' conviction could prove telling.
"For this semi-final, it is clear to me that Portugal have the better players – Cristiano, Nani, Renato Sanches, Joao Moutinho," Ancelotti said.
"Wales have Gareth but they are without Aaron Ramsey. Wales have a strong team though, and that can carry you through a lot of difficult moments.
"A lot will rest on Gareth inspiring his team-mates, but when he says that he believes in them all, you know that he is telling the truth."
