Like most people, Alonso is far and away my number one choice. He feels like, at the minute, the only one who doesn't fill me with overwhelming pessimism.
As of right now, nobody else excites me. The likes of De Zerbi, Frank or Nagelsmann could all theoretically be successful, but 9 years of Klopp not only succeeding on the football pitch but cultivating a proper emotional relationship with the fans and the city leaves me feeling a bit cold to all 3 of them.
