Celtic manager Neil Lennon has insisted that he is not concerned with how Barcelona will approach their Champions League game against Benfica.
The Spanish giants have already qualified for the last 16 as Group G winners, while Benfica and Celtic are in the running to join them.
Lennon's side will host Spartak Moscow at home on matchday six, while Benfica will travel to Barcelona.
"I can't comment on other teams, other teams' lineups and other managers, they have to do the best for their own clubs," BBC Sport quotes Lennon as saying.
"I'm only focusing on the Spartak game, I won't even look at the other result until after the 90 minutes."
Both Celtic and Benfica have collected seven points from five matches.
