Arsenal’s Europa League quarter-final tie with Napoli is “still 50-50” according to Gunners boss Unai Emery, despite his side winning the first leg 2-0 at Emirates Stadium.
Aaron Ramsey converted Ainsley Maitland-Niles’ pass to finish off a good team move and give the hosts the lead.
Kalidou Koulibaly then scored an own goal when he deflected Lucas Torreira’s shot past goalkeeper Alex Meret.
The impressive Meret stopped the Gunners winning by more.
Napoli, who are second in Serie A, host the Gunners in the second leg next Thursday at the San Paolo Stadium (20:00 BST).
Chelsea escape with victory in Prague!
Chelsea boss Maurizio Sarri said he was pleased with how his side “suffered” before beating Slavia Prague in their Europa League quarter-final first leg.
Marcos Alonso’s late goal secured a 1-0 win from a difficult match in Prague.
Sarri said his side have improved from earlier in the season, when they would “immediately concede” in difficult moments.
“In the past we were not able to suffer in the difficult moments of a match,” said the Italian.
“Now we are able to stay in trouble and suffer without conceding.”
An under-strength Chelsea struggled to find any rhythm for large spells, but grew into the game after Eden Hazard was introduced off the bench just before the hour mark.
Alonso timed his run perfectly to meet Willian’s right-wing cross with a firm header four minutes from time at the Eden Arena.
The second leg at Stamford Bridge takes place on 18 April.
Here are all the results from last nights Europa League first leg ties:

Sparta Prague – Chelsea 0-1
Villareal – Valencia 1-3
Benfica – Eintract Frankfurt 4-2
