Rodgers, who takes his team to Tynecastle aiming to extend their unbeaten domestic run to 70 games, admits ability is essential but it isn’t enough on its own to make them worthy of joining his Invincibles.
He said: “In some ways, there’s not a big difference in terms of players.
“I’ve seen a number of players in Scotland who could probably play for Celtic.
“Then when you ask about them, the mentality’s not there – and that’s the big difference.
“Some players up here will be as quick as our boys and equally as skilful but, when it comes to it, how are they mentally?
“It’s a tough ask because they won’t cope with the demands our boys face every day just to lead the life – diet, nutrition, preparation, concentration, drive, resilience.
“This is what it takes when you want to play for the big clubs.
“Our lads are putting it down every single day so when they go into a game and are asked questions, you know they are ready for it.
“You have to have that resolve and the mindset we have given them – you keep fighting to the very end.”
