West Ham became the second Premier League club to move into the knockout round as Soucek's late goal saw off Serbian minnows Backa Topola 1-0.

Soucek's 89th-minute volley from Maxwel Cornet's cross sealed the victory that put his team top of Group A.

The Czech midfielder has scored in his last five matches for club and country, after also netting a last-gasp winner at Burnley last weekend.

Second-placed Freiburg thrashed Olympiakos 5-0 to join West Ham in the knockout round.

The Hammers will seal first place if they avoid defeat against the German side in east London in December.
