The big news of the day -- Champions League matches aside -- is the announcement that Jürgen Klopp will be leaving Borussia Dortmund at the end of the season. The German manager found significant success during his time at the Westfalenstadion, but a trying first half to this season made moving on not just possible, but perhaps even necessary.

The news has left clubs across Europe scrambling to figure out if they can get their hands on Klopp, who twice won the Bundesliga with Dortmund and returned them to their status as one of Germany's elite clubs. Napoli will definitely be among the clubs trying to get him -- especially since they made the same effort two years ago before hiring Rafa Benitez -- but will be facing some very, very stiff competition along the way.

While Napoli can offer a tempting job for many managers, several other high-profile clubs either will or could likely have job openings to offer Klopp this summer as well. In England, Manchester City seems a near-lock to fire Manuel Pellegrini, while Arsene Wenger might -- probably won't, but might -- retire from his role at Arsenal. Real Madrid could dump Carlo Ancelotti if los Merengues fail to win anything. Paris Saint-Germain's managerial chair has been red-hot under Laurent Blanc all season.

That's some heady company to be competing with, and it means that it's very unlikely that Klopp will be patrolling the touchline at the San Paolo next season. It's fun to dream on, though, as the bespectacled German is an entertaining manager and quite good at what he does. If anyone could help Napoli take the needed "next step," it''s Klopp. Hopefully whoever Napoli do wind up with can do anywhere near as good a job as he would be capable of.
