Celtic manager Neil Lennon insists his side are not in Barcelona just to enjoy the trip as they prepare for Tuesday's Champions League showdown.
"It is exciting times for the players and the club and the supporters as well," he said. "But we are not here for a holiday. We are not here for the tourist attractions.
"We are here to play football. We are going to be in for a tough 90 minutes but we want Barcelona to be in for a tough 90 minutes.
"We need character and mental strength and allied to that the players need to play at the peak of their abilities to overcome what is probably the best team in the world at the minute."
The Scottish champions are quoted at 25/1 by Sky Bet to claim a surprise Group G victory at the Nou Camp but Lennon believes the pressure has eased after their 3-2 win at Spartak Moscow last time.
He said: "There is always pressure going into any game but what we have done is give ourselves a nice cushion, a platform.
"Maybe we didn't visualise getting a result in Moscow but this is the ultimate test, away from home against Barcelona.
"We haven't really budgeted for anything out of this game but who knows?
"The players are young and fearless. There is a bit of naivety about them at times but there is plenty of international experience and we saw that in Moscow."
