The Croatian, who was accompanied by French coach Zinedine Zidane, spoke at the press conference on Juventus's Champions League quarter-final.
"There is no difference," he said. "There is no difference. It's a great duo who works for the team. They are doing everything they can for Real Madrid."
Modrich went on to say: "Bill? Is one of the most important pillars of the team, but I do not interfere in the issue of participation in the games or not, this is for Zidane alone, the coach decides it. "
"Bill has been very good in the last few games, we know his quality and we believe in his ability, as I said, he is an important player for us," said Modric.
The draw resulted in a firefight that would bring Real and Juventus into the quarter-finals of the UEFA Champions League, a repeat of last year's final, which saw Mirngi sweep the old lady with a four-goal lead.
