For their friendly win over Athletic Bilbao, Modric received a huge round of applause when he entered the field - something which Crouch hopes could prove pivotal in keeping the star at the club amid reports that Chelsea weighing up a fresh £30million-plus bid for the player.
"I think he might have been a bit concerned about which way it would go but he got a great reception," Crouch said.
"That certainly makes it harder for him that the fans are right behind him. He knows that the fans here love him and hopefully he can stay here for as long as he can.
"He's going off for international duty now and we were saying to him: 'make sure we see you on Thursday' and we hope he does.
"He is a top player. We love him at the club. He is a great lad to have about. We all want him to stay."
