Bukayo Saka scored as Arsenal came from behind to secure a draw in the first leg of their Europa League last-32 tie with Portuguese side Benfica.

The Gunners failed to take a number of first-half chances, with Pierre-Emerick Aubameyang unable to continue his form after a hat-trick against Leeds United last weekend.

And Benfica punished the away side by scoring from the penalty spot after 55 minutes.

Emile Smith Rowe was adjudged to have handled in blocking Diogo Goncalves' cross, leading to a penalty that Pizzi converted.

But the lead lasted just two minutes after Cedric Soares' cross was converted by Saka.

The England international is now the youngest Premier League player to have reached double figures for goals (10) and assists (16) across all competitions.

Speaking after the game, Mikel Arteta said Arsenal deserved more from the game.

"We were very dominant and created some big chances," said Arteta. "We have to be more ruthless. It was disappointing the way we conceded the goal. We gave them the ball then it was 1-1 and all to play for.

"We conceded a corner then from the corner we did not react quick enough and conceded the penalty. Looking at it it's difficult to judge. We had a great reaction and scored a great goal.

"We tried to maintain the level. Both teams dropped in the last 20 minutes. But overall we should leave the ground with more."
