“Of course I know all the Juventus players very well, they are very strong. It’s going to be a tough game against Italy. They are without doubt the best team in the tournament,” the 34-year-old said.

Powerful defender Thuram is one of five players in the current side who lifted the Jules Rimet Trophy in 1998.

“It’s just crazy,” he said.
“I shouldn’t even be here. I didn’t want to come back but the coach convinced me to return against my better judgement and here I am once again in a World Cup final. Football is just wonderful.”
