Europa League: Unbeaten Bayer Leverkusen put treble bid on the line against West Ham

Bayer Leverkusen put their unbeaten season and their treble ambitions on the line when they host West Ham United in a Europa League quarter-final first leg tie on Thursday night.

Xabi Alonso's team are yet to lose this season, winning 36 and drawing five of 41 games across all competitions. Last weekend's 1-0 win at Union Berlin means three points against Werder Bremen this Sunday at the BayArena will secure the club's first-ever league title.

As well as their Europa League campaign, they have a German Cup final against second division Kaiserslautern to look forward to in May, with there now being a realistic chance that Alonso's side could win more trophies this season than in the club's entire previous history.

To say such success is unprecedented would be a massive understatement. Despite being a big name in German football, Leverkusen have a relatively bare trophy cabinet, with just two major honours: the 1988 Uefa Cup and the 1993 German Cup. Club bosses are also said to be fraught with concern they have nowhere suitable to host fans when celebrating their successes at the end of the season.

Alonso, however, will hear no talk of parties. His steadfast refusal to get carried away by their record-breaking form has been a theme of the season.

"We're in a super situation in the cup, the Bundesliga and we want to also do well in the Europa League and achieve as much as possible," Alonso said after Saturday's win took his side 16 points clear of closest domestic challengers Bayern Munich.

"On Thursday we've got West Ham at home. It's not the right moment to think about the weekend. We'll have time, but we just need to be a bit more patient."

The luck of the draw means Leverkusen would face Liverpool in the final in Dublin
