FCSB gave them a scare last week and Moyes will need his team to start much quicker should he have any hope in trying to replicate the success of last season on the continental front.
After a tricky start to the season, it’s time for West Ham to truly click into gear.
While there are a lot of new players to knit together, big spending brings with it huge pressure, and a meeting with a team outside Europe’s top five leagues in Silkeborg should – on paper at least – be a formality.
Still, that is rarely how things work, making for a interesting affair later tonight.
Here’s where to watch the action.
