Why would any talented football player want to sign for Leverkusen in the first place? The club has no winning history in the Bundesliga. No European relevance since the famous Zidane goal. The city of Leverkusen only has 160K inhabitants in a country of 80 million people. Basically you'll get to live in a suburb of Cologne. There's a pharmaceutical company that brought Aspirin on the market that is headquartered there but it doesn't seem like a fun place to me.
