The manager added: “They need to get to know me. They have to believe in me rather than just what I say. There’s no better chance for that when we’re together 24/7 and have plenty of opportunities to connect on and off the training pitch. We have some friendly games as well so I’m looking forward to it.

“I see friendly games as an extension of our training and our pre-season programme. It’s an important part because I want to see improvement and progress in our football during games.

“We have some really good games and challenges and they’ll be treated as part of the pre-season programme. It’s about trying to make sure we have the processes right and that the players have a clear understanding of how I want them to play.”

Ange Postecoglou has already made one addition to his squad, with the arrival of defender Osaze Urhoghide from Sheffield Wednesday, and he has a clear idea of the type of player he wants to bring to the club.

“Sometimes we fall in the trap of just signing footballers,” he said. “We’re signing people and how they are as a person is important to me. What they’re own feelings are about the club is important.

'Celtic is a club with great traditions and history but it’s also a club of great standing and high values and I won’t let anyone use this club as a vehicle for individual purposes.'

“They need to understand there’s a responsibility when you come here and you can create and experience some fantastic things here. I want people to come to Celtic because they want to play for this football club, not because of individual ambitions to do something else.

“What I’ll guarantee them is they’ll develop to their full potential here.”

The UEFA Champions League qualifier against FC Midtjylland is looming on the horizon, with the first leg at Celtic Park on July 20, but the Celtic manager is concentrating on the training sessions and friendly matches that will come before then.

“My most narrow focus is on each day,” he said. “If you look too far ahead, you miss the opportunity to improve now. For me, today is the most important day today and then tomorrow will be the most important day after that. Hopefully, when we get round to the game against Midtjylland, we’ll be ready.”
