I wouldn't say so.
Both teams ended up with nothing yet we went all out for one competition, Bayer went all out for three.
In fact if we're to nit pick, them finishing as runners up in the Bundesliga, CL and DFB Pokal is better than us finishing third in the Prem.
And I would say there was, because Leverkusen were directly responsible for their season falling apart by flogging their team to death, while we looked to preserve our team's stamina and our season only fell apart after the league slipped away with a pair of critical suspensions adding to it
Most importantly, though, look at how Leverkusen did in 2002-3, which while it would be remiss to mention they had some key players spirited away - Ze Roberto to Bayern (because of course...) and Michael Ballack to Chelsea - but the level of their slump was alarming
Bundesliga: 2nd to 15th (or missing the title by a point to avoiding relegation by four)
Champions League: final to second group stage
German Cup: final to semi-final
In comparison, look at our 2016-17 compared to 2015-16
Premier League: 3rd to 2nd
Europa League: last 16 to not having to book hotels in Baku or Tiraspol
Champions League: DNQ to group stage
FA Cup: fifth round to semi final
Season Killer Cup: third round to fourth round
We had improved results in literally every single competition (and just so happened to bury the "Poch doesn't care about domestic cups" Narrative that got endlessly repeated by people who don't know how to use Google properly...) entirely because we didn't flog the team to death not just physically but also mentally - that didn't happen until we went all-in for the Champions League only to come up against our greatest foe: a Slovenian ****wit who can't tell his armpit from his elbow, let alone understand the handball rule
