Dele Alli has urged Tottenham to "put their chances" away during Tuesday night's crucial Champions League clash against Bayer Leverkusen.

Tottenham currently sit second in Group E and will tighten their grip on a qualifying place if they are victorious against Roger Schmidt's side.

But Spurs warmed up for their trip to Germany with a frustrating 1-1 draw against West Brom, which saw the north Londoners squander several chances.

Mauricio Pochettino's side are unlikely to be able to be similarly wasteful at the BayArena and Alli is adamant his teammates must be clinical as they go in search of their second successive away victory in Europe's elite competition.

"I can't wait for the Champions League, get back out there, hopefully get some minutes and try and get the win," he told the club's official website.

"We have to pick ourselves up. The boys will be disappointed we didn't get all three points [against West Brom].

"But there was a lot of positives. We played really well, maybe we didn't put away the chances we had but we were creating chances, which is always a positive.

"Next game we have to make sure we put them away," Alli insisted.

With Harry Kane injured perhaps it is not surprising Tottenham have occasionally appeared to lack a clinical edge in front of goal in recent weeks.

But in-form forward Heung-min Son only played 19 minutes at the Hawthorns and appears to be primed to lead Tottenham's line against his former club in midweek.

The South Korea international spent two years at Leverkusen and was keen to return to Germany this summer before eventually being persuaded to stay put at White Hart Lane.
