"He's been really good," said Le Bris about Alderete.
"He's a bit different. His character, the way he trains every day, his connection with his teammates. He is a bit older and with a different culture.
"His job as a centre-back is probably a bit different then a midfielder, a striker or winger but he's been really important to us and the way we want to play.
"When the opponent wants to go direct, he is really good at managing duels and long balls inside the box. He has this ability to defend and doesn't need to force it.
"He likes defending the box. His left foot is really good too.
"Sometimes, he can be without a good level of energy to give the right tempo but it's because he is so skilled so it's easy for him. I think he has improved this part during the season."
