Neil Lennon has played down early talk of Celtic progressing to the knockout stages of the Champions League.
The Scottish side recorded their first ever away win in the competition at Spartak Moscow on Tuesday night, with Georgios Samaras scoring the winner in a 3-2 victory.
Added to a 0-0 opening home draw with Benfica, some fans are already drawing up the permutations for Lennon's side to further upset the odds and reach the last 16 of the competition.
Lennon though insists he and his side are keeping their feet on the ground, with four matches left to play and a double header against Barcelona looming.
"It is a huge step for the club," he said. "It is our first away win in the Champions League so we have broken a record.
"It is fantastic but there is a lot of football to be played in the group.
"We have two home games and Benfica and Barcelona away so it is still an open group for second place as far as I am concerned."
Celtic took the lead through Gary Hooper 12 minutes into the match in Moscow, only for goals from Emmanuel Emenike either side of half-time to put the hosts in front.
Juan Insaurralde's red card for denying Hooper an obvious goal scoring opportunity gave the visitors a way back in to the match, which was taken as James Forrest's shot was turned in by Spartak defender Dmitri Kombarov.
Samaras' late header clincher gave Lennon his third consecutive away win in European competition, having negotiated qualifiers with HJK Helsinki and Helsingborgs IF.
He added: "We are still novices in this tournament but a few more performances like that wouldn't do us any harm at all.
"Every one of the players was a credit to the club."
