Eintract Frankfurt 1-4 Bayer Leverkusen

After Frankfurt's Hugo Ekitike and Spurs' Mathys Tel traded first-half chances, home goalkeeper Kaua Santos' nasty collision in the box with James Maddison brought Solanke to the spot.

Without a goal since January, Solanke made no mistake, giving Spurs the lead in front of Frankfurt's raucous Nordwestkurve.

The win will prove a stay of execution for Postecoglou, keeping alive Spurs' chance of reaching the final in Bilbao along with the coach's oft-maligned guarantee of winning a title in his second season at a club.

The loss ends Frankfurt's hopes of returning to Spain to again lift the Europa League title, having done so three years ago in Seville.

Despite the defeat, Frankfurt sit third in the league and are on track for their best league finish since the mid-1990s.
