Bukayo Saka rose to the rescue yet again as Arsenal came from behind against Benfica in Rome to pick a point
But Mikel Arteta moaned that the Gunners missed a golden opportunity to book their place in the last 16.
Saka struck his fifth goal in 12 games to level this last-32 tie up after Pizzi scored from the spot for the Portuguese.
But Arsenal were completely dominant until Emile Smith Rowe’s dopey handball gifted their opponents a second-half penalty.
Arteta said: “I think it was a missed opportunity. We were dominant. Away from home you have to be more ruthless. We could be in a much better position.
“It was disappointing the way we conceded the goal. Both teams dropped in the last 20 minutes. But overall we should leave the ground with more.”
Saka said: “We should have won. Definitely. We had a lot of chances. We’re frustrated. We dominated the whole game.
“They scored with a lucky penalty which I don’t think was a penalty. He’s had to react to it. We dealt with it well, got a goal back and could have won.”
