David Moyes is urging West Ham to avoid having to add two fixtures to their packed schedule by finishing top of their Europa Conference League group.
Runners-up have to play a two-legged knockout tie to reach the last 16, whereas the top teams automatically make it through. The Hammers lead Group B with three wins from three and face Anderlecht at home tonight.
Gianluca Scamacca scored the winner away to the Belgians last week as a substitute and the £35.5million striker is expected to start tonight, with Michail Antonio suffering from the flu.
