Slavia Prague scored a dramatic stoppage time equaliser to leave Arsenal’s Europa League ambitions hanging in the balance.
Substitute Nicolas Pepe thought he had earned the Gunners a slender quarter-final first-leg advantage when he broke the deadlock in the 86th minute.
The second leg in Prague takes place next Thursday and Gunners boss Mikel Arteta, despite his side conceding so late, still believes they will progress to the semi-finals.
“The mindset has to be to go there and score goals and win the game because we have to score if we want to go through,” said the Spaniard.
“I totally believe that we can go there and win the match, if not I wouldn’t be sitting here.”
