Arsenal are lucky to get a corner as Edmond Tapsoba needlessly heads the ball behind when his keeper was about to get it.

And Shkodran Mustafi heads wide from Dani Ceballos' cross. That's his second headed miss.

Great quick feet from Emile Smith Rowe, who looks a really talented player, to skip past a few challenges but they can't make anything of it.

The second half begins.

That feels like a big statement from Unai Emery.

Arsenal make two half-time changes. Dani Ceballos and Matteo Guendouzi replace young English midfielders Joe Willock and Ainsley Maitland-Niles.

Manchester United manager Ole Gunnar Solskjaer: "In the second half I thought we dug in really well in the box. They [Partizan] played well and made us defend too deep - I'm not happy with the defending at the front. It's been one of our strengths this season but it was non-existent in the second half. It needs sorting out.

"I thought Jimmy [Garner] grew into the game. He got tired at the end, which is natural. Brandon [Williams] was man of the match.

"He was absolutely excellent. Fantastic attitude, great attitude, great in the air, brave and he gets us a penalty by driving forward with the ball so we have found a left-back there."

This is only the second time Vitoria Guimaraes have scored more than once in an away game in Europe. This is their 40th such match.

Marcus Edwards' eighth-minute opener is the earliest goal Arsenal have conceded in European competition since Edinson Cavani netted for Paris St-Germain after 42 seconds in September 2016.

The two players with the fewest touches in the game so far? Arsenal goalkeeper Emiliano Martinez (9) and Vitoria goalscorer Bruno Duarte (11).

Ainsley Maitland-Niles is getting a bit of a hammering on social media from Arsenal fans. He gave away the ball in midfield for the second goal.

Arsenal have conceded more goals in this game than their previous seven Europa League home matches combined (one).

A bit strange as the half-time whistle goes exactly on 45:00 despite a few goals. Arsenal trail.

Corner to Arsenal but Shkodran Mustafi doesn't make proper contact with his header and Vitoria get it away.

Almost a third for Vitoria as Davidson flashes a shot just wide from about 20 yards out. It wasn't dissimilar to the effort which led to the second goal.

Manuel Lazzari has just given Lazio the lead against Celtic.

Luke: Well you can see why Martinelli trains with the Brazil squad, direct with the ball and gets into the right areas, but great cross from Tierney what Arsenal have needed all season a full-back!

Gabriel Martinelli has been directly involved in six goals in three starts for Arsenal in all competitions, scoring five and assisting one.

Immediate chance for Arsenal again as Emile Smith Rowe picks out Gabriel Martinelli, but he drags his shot just wide of the far post.
