Honestly, Leverkusen went 51 games unbeaten, even though they did ended up losing at the finals, that doesn't mean that they had a bad season overall, winning the league at Bundesliga is already a huge achievement, no team achieved that over Bayern in over a decade, so being able to do that alone is so greatest in my perspective.
Plus, they are going to play the cup game, which I really feel like they are putting some immense pressure on themselves now, they had confidence that they can beat anyone, but after Atalanta I am damn sure that they are not entirely sure.
But to be fair, they are playing a team one division below so it would be even bigger shock if they lose. They will most likely finish with a double, and that is going to be a great thing for them, we shouldn't judge them on just one game.
Seriously, that Leverkusen loss was shocking. Season opener in Europa League final? Ouch. Thats soccer, right? Keeps us wondering. Dont dismiss these men. Ending Bayern's streak and finishing 51 games unbeaten was fantastic. Its astounding whichever way you slice it. Cup finals are stressful, especially when you're aiming for the double. But these people fight. They'll recover and learn. They can redeem themselves against a lower-division team and complete the season with a trophy. While this loss hurts, this Leverkusen team is real and has a bright future under Xabi Alonso. Everyone can look forward to that.
