West Ham defender Angelo Ogbonna slides through the back of Jay-Roy Grot and is lucky to avoid a yellow card on his return from injury.

West Ham have a few things to tighten up after this. Jay-Roy Grot is allowed to run in behind too easily but Alphonse Areola makes himself big and saves with his legs.

The second half begins eventually. There was a slight delay as Jarrod Bowen had to add some tape to his socks for some reason.

West Ham bring on Pablo Fornals for Manuel Lanzini at half-time.

West Ham will surely want to get another couple of goals in the second half and have the tie wrapped up before they go to Denmark next week.

Viborg had more possession and more shots but you can't deny West Ham deserve to lead.

The half-time whistle goes. So far so good for West Ham and Gianluca Scamacca, who has his first goal for the club.

Viborg end the half with their first shot on target but Jan Zamburek's effort from outside the box is comfortable for Alphonse Areola.

Two minutes added on.

Justin Lonwijk's brother Nigel is on loan from Wolves to Plymouth this season.

Viborg's two chances have come from West Ham losing the ball in midfield. This time Justin Lonwijk curls just wide of the far post from 25 yards.

Maxwel Cornet is offside as he runs onto a ball down the left. He swapped the claret and blue of Burnley for the claret and blue of West Ham this summer.

Twice in a couple of minutes, West Ham keeper Alphonse Areola is off his line quickly to deal with a threat.

He'll be hoping to play some more league games this year.

Viborg aren't causing West Ham many problems here, a cross sails harmlessly out of play. Just the one chance for the visitors so far.

Viborg lose right-back Daniel Anyembe to injury. Teenager Anton Gaaei takes his place.

Viborg keeper Lucas Lund Pedersen punches a corner into a crowd of players but luckily it lands to his defender and not a West Ham player.

The crowd roar as Manuel Lanzini gets the ball in midfield, turns and bursts forward.

Gianluca Scamacca takes over on the wing, cuts in and then blasts in a 25-yard shot which is parried by the keeper.

Maxwel Cornet scuffs the rebound, which he should bury really, but he is offside anyway so it wouldn't have counted.

Great for Gianluca Scamacca to get on the scoresheet so early for the Hammers. That will do the Italian a world of good. And West Ham too.

West Ham are just knocking the ball around now.

Maxwel Cornet and Gianluca Scamacca cost a combined £48m in the summer. Hard for a mid-table Danish team to deal with that.
