Villa almost add a third as two-goal Donyell Malen picks out Jadon Sancho, whose shot is blocked.

Celtic are halfway to a priceless victory in Rotterdam.

You feared the worst for Martin O'Neill's side when Ayase Ueda gave Feyenoord an early lead, but goals from Yang Hyun-Jun and Reo Hatate have turned the game in Celtic's favour.

After winning just one of their opening four Europa League games, Celtic really need the three points tonight.

Play is continuing but apparently there's more trouble in that away end.

They've said there are four minutes of stoppage time but I don't think that's accurate really. For one thing we're into 45+3 now - and the goal was scored in 42. And no football was played between those times.

Play is finally back under way.

The referee is talking to both managers. It's been about four minutes since a ball was kicked (into the goal).

Poor defending from Young Boys, Donyell Malen always wanted to come over onto his right foot.

He limited his touches in the box, knew what he wanted to do and took it early past the goalkeeper.

Game over.

According to the TV commentator, fans are throwing seats at the police. I think it's all happening in the away end.

Play hasn't restarted since the goal because of this crowd trouble.

Young Boys captain Loris Benito has gone over to his club's fans to ask them to start behaving. There is fighting in there and the police are getting involved.

Morgan Rogers steps over Lamare Bogarde's cross but Jadon Sancho isn't there to meet it behind him.

Victor Lindelof heads away a Young Boys cross. The visitors haven't even had a shot of any kind yet.

I understand Young Boys' approach becuase they are coming up against an in-form team that can hurt them all over the park.

They aren't going to come out, even though they are 1-0 down now. They seem quite content with not getting hammered here.

They have been beaten quite heavily in previous games, so they will probably take a 2-0 loss to come away from here with a bit of respect.

Hope I don't play any BBC Sport readers online tomorrow as I've given my tactics away a bit there.

Villa have had 46% of their attacks down the left, compared to 30% on the right. It's like when you play Fifa and you just keep going down the wing on the near side of your screen - and then do the other side in the second half.

Donyell Malen has scored seven goals for Villa and the Netherlands since the start of last month.

Unfortunate for Villa as Ian Maatsen charges into the box but then takes an extra touch and he's gone too wide. His cross isn't great.
