Luis Suárez is expected to discover early next week whether he faces sanction from Uefa for an alleged stamp during Liverpool's Europa League exit against Zenit St Petersburg on Thursday.

Zenit players accused Suárez of stamping on the Slovakian defender Tomas Hubocan in the 88th minute of Liverpool's 3-1 win, a result that eliminated Brendan Rodgers' team on away goals. The Liverpool striker caught Hubocan twice after the left-back fell while shepherding the ball out for a goal-kick – on his leg and lower back. But neither the Dutch referee, Björn Kuipers, or his additional assistant behind the Kop goal deemed the incident deliberate.

Uefa has confirmed, however, that Suárez could face disciplinary action should Kuipers suggest in his official match report that it reviews the incident. European football's governing body should receive a report within 24 hours of the game and will decide whether its disciplinary committee is required at the start of next week. Uefa could then take retrospective action against Suárez and he could be banned for up to three European matches if found guilty of violent conduct.

The Uruguay international scored his 24th and 25th goals of an impressive individual season against Zenit, who now face Basel in the last 16, with Joe Allen also on the scoresheet for the first time for Liverpool since his £15m move from Swansea City. Defeat ended Liverpool's last hope of silverware and they trail Tottenham by nine points in the pursuit of Champions League qualification. But Allen says the campaign will not peter out following the club's European exit.

"That might be a concern from the outside," said the Wales international. "But within the dressing room there are enough characters and big personalities that the attitude and approach won't change and we look forward to some good performances before the end of the season. There's no trophy for us to play for this season, which is tough for a team like Liverpool to take, but there's plenty to play for in terms of the Premier League. There are lots of points to try to get and we'll look to pick up as many as we can."

By his own admission Allen has struggled of late at Liverpool but he produced an encouraging display against Zenit and his influence was missed following a 60th-minute substitution.He added: "It was a lot better than it has been recently which was a positive on a personal note. It was a shame it wasn't a performance that could carry us through to the next round but hopefully I can build on that performance. I would like to think I've got a big part to play between now and the end of the season and hopefully I can get the standard of my performance back up there."
