Petr Cech hopeful of Arsenal progress despite first-leg defeat to Barcelona

Lionel Messi shoots past Petr Cech to score the first goal in Barcelona's 2-0 win at the Emirates

Petr Cech refuses to write-off Arsenal's chances of reaching the Champions League quarter-finals, despite Tuesday's 2-0 first-leg defeat to Barcelona at the Emirates.

Arsene Wenger claimed after the game that the Spanish side were "95 per cent through" after two second-half goals from Lionel Messi gave Luis Enrique's side the advantage ahead of the second leg in Spain in three weeks' time.

No side has ever won a Champions League tie after losing the first leg at home by a two-goal margin, but goalkeeper Cech insists Arsenal are not done yet.
