West Ham United saw a 1-0 home win over Olympiakos Piraeus to retain top spot in Europa League Group A, while Olympique de Marseille won 2-0 at AEK Athens to remain first in Group B on Thursday.
West Ham lost 2-1 away to the Greek side a fortnight ago but their win at the London Stadium put them level on nine points with second-placed Freiburg, who crushed bottom side Backa Topola 5-0. Olympiakos are third with four points.
"If I was being honest, I don’t think we made enough chances or opportunities and I need to look to see why that was the case," West Ham manager David Moyes said.
Lucas Paqueta broke the deadlock in the 73rd minute with a deft left-foot volley following a delightful James Ward-Prowse chip over the defence for his third goal in European competition this season, which was confirmed after a VAR review for offside.
The West Ham fans then held their breath late on as the visitors nearly equalised when Mady Camara's close-range header struck the post when he should have scored.
Marseille secured a second victory with their win in Athens thanks to goals from Chancel Mbemba and Ismaila Sarr.
Mbemba opened the scoring with a header from a corner after 25 minutes and Sarr struck three minutes into stoppage time.
