Ostersunds FK 2-2 Athletic Bilbao

Ostersunds manager Graham Potter has led his team to seven points from their opening three Europa League games

English midfielder Curtis Edwards struck a 20-yard volley as Swedish minnows Ostersunds drew with Spain's Athletic Bilbao to maintain their unbeaten start in the Europa League.

It was an eventful evening in the competition as Bilbao's Basque rivals Real Sociedad romped to a record away win - 6-0 at Macedonian side Vardar - while thick fog temporarily stopped the Group F match between Czech side Zlin and Danish visitors FC Copenhagen.

Ostersunds once again took the headlines, though, despite being denied a famous victory against the eight-time La Liga champions by Inaki Williams' 89th-minute equaliser.

Former Middlesbrough trainee Edwards, who moved to Sweden after playing for Northern League semi-professional side Thornaby, put Ostersunds within touching distance of a comeback win after Spain striker Aritz Aduriz had given the visitors the lead before half-time.

Ostersunds, managed by former Stoke and Birmingham full-back Graham Potter, levelled against the 2012 Europa League finalists through Salisu Abdullahi Gero after the break.

Edwards, 23, volleyed in shortly after as they looked set to preserve a 100% record at the halfway stage of Europe's secondary club competition.

But Williams tucked in Aduriz's square pass as Athletic avoided a sixth defeat in their past seven Europa League away games.

Despite being unable to clinch victory, the point puts Potter's side in a promising position to qualify for the knockout stage on their European debut.

Ostersunds were in the Swedish fourth tier when Potter took over in 2011 and have been promoted three times before winning the Swedish Cup and qualifying for Europe for the first time.

Athletic, who finished seventh in La Liga last season, are five points adrift of the group leaders after two draws and a defeat in their opening three games.

Sociedad hit six and Milan lose 100% winning start

Willian Jose scored more goals in an hour against Vardar than he has netted in six La Liga games this season

Brazilian forward Willian Jose scored four times in the space of 25 minutes as Real Sociedad thrashed Vardar.

It was the biggest away win in Europa League history as Sociedad became only the fifth team to win by a six-goal margin in the competition.

Sociedad are second in Group L, three points behind Russian side Zenit St Petersburg, who beat Rosenborg to maintain their 100% start.

Seven-time European champions AC Milan were unable to clinch a third straight Group D win after failing to break down Greek side AEK Athens at the San Siro.

Milan coach Vincenzo Montella was hoping a victory would ease some of the pressure building on him following Sunday's 3-2 derby defeat by Inter - the Rossoneri's third straight defeat in Serie A.

Ukrainian side Dynamo Kiev and Portugal's Braga also lost their 100% winning records.

Dynamo were held 2-2 by Swiss visitors Young Boys, while Braga were beaten 2-0 at home by Ludogorets.

Mario Balotelli opened the scoring for Nice when they hosted Lazio in a Group K match between two sides with 100% records.

But the Serie A side fought back to win 3-1 through goals from Felipe Caicedo - another former Manchester City striker - and a second-half brace by Serbian Sergej Milinkovic-Savic.

Germany's Hoffenheim earned their first European win at the fifth attempt, beating Turkish side Istanbul Basaksehir 3-1.

Elsewhere, Steaua Bucharest beat Hapoel Beer Sheva to continue their 100% start and close in on the knockout phase.

Nothing to see at Zlin...

Visibility became increasingly difficult in the second half of Zlin's match against FC Copenhagen

The game was suspended with just under 20 minutes left because of thick fog in Olomouc with the score at 1-1.

Play resumed about 15 minutes later and neither side could find a winner.

Referee Oliver Drachta stopped the game midway through the second half
