Manchester City star Bacary Sagna has warned his superstar team-mates that they write-off a wounded Celtic side at their peril.
Brendan Rodgers' side host the in-form Premier League leaders in the Champions League on Wednesday off the back of a brutal 7-0 battering in Barcelona.
However, Sagna believes that Nou Camp humiliation will leave the Scottish champions even more desperate to make their mark on the competition when they kick off their first Group C home match against Pep Guardiola's star-studded side.
The 33-year-old has played at Celtic Park once before, when a fortunate William Gallas strike and a Gary Caldwell own goal secured a 2-0 Champions League qualifying win for Arsenal in August 2009.
