"It's always a good atmosphere and relationship between the two clubs' supporters and I'm sure it will be a good game," he says.
"We have had a couple of games with them over the past few years and they've come out on top, so I think we'll have to change that. Even though it's only a friendly we want to win the game.
"Playing teams like Celtic, Porto and Roma will help sharpen us up for the start of the season. We are playing some excellent teams and we'll see how we get on in the games.
"I think this is an excellent tournament. We have the European champions in Porto, Roma who finished second in Serie A and Celtic who have done really well in Europe in the past couple of years."
