That's a shame for Dundalk because Arsenal haven't really put them under any real pressure.

And Arsenal are in front thanks to a mistake from Rogers. The keeper goes to punch from a corner, he mucks it up, it hits a Dundalk player, and Nketiah fires into the net.

Start of match
PRVW
Nathan Oduwa is on the bench for Dundalk. He used to play for Spurs.
PRVW
This has to be one of Dundalk's biggest matches.
PRVW
Arsenal will be hoping to build on that win against Rapid Wien tonight. Dundalk lost 2-1 to Molde last week.
PRVW
This is Arsenal's first ever match against an Irish team.
PRVW
Dundalk have played English sides 6 times in Europe. They lost 4 times to Liverpool, drew with Tottenham and also lost to them.
PRVW
I don't expect anything other than an Arsenal win tonight. Yes, they have made lots of changes but Dundalk have only qualified for the group stages once and didn't win an away game. But who knows, there may be an upset.
