Celtic manager Neil Lennon wants his players to not even think about the fact they are taking on Barcelona tonight.
The Hoops last night left Glasgow for Spain as they prepare to take on the Catalan giants at the Nou Camp in the Champions League and Lennon has urged his team to ignore Tito Vilanova's stars in the tunnel prior to kick-off.
"I won't be in the tunnel when the teams walk out, but I want them to look straight ahead, not at the side," he said.
"I want them to focus on getting a foothold on the game at some stage.
"We will respect them, there's no doubt about that, but we'll have to play aggressively at times."
He added: "I think it's better to play with a wee bit of fear, a bit of edge.
"It gets the adrenaline going quicker and it sharpens the mind."
