Celtic manager Neil Lennon has claimed that his players must do their best to contain Barcelona if they are to get a result in Tuesday's Champions League clash at Parkhead.
The Scottish champions welcome the Spanish giants to Glasgow in Group H.
"It will be, at times, containment," Goal.com quotes Lennon as saying. "Limit them to as few chances as we possibly can.
"They're not like any other team. Barcelona, in my personal opinion, are a class above, and have been consistently the best club side for 10 years now.
"Barcelona don't change their system, their style of play and that is what they believe in. When they get the ball in the final third, the speed of the ball is phenomenal at times."
Celtic lost their opening match of this season's Champions League 2-0 against AC Milan, while Barcelona ran out emphatic 4-0 winners over Ajax.
