The challenge Liverpool face in finding a long-term replacement for Jürgen Klopp is made clear when assessing the data on head coaches in global football and filtering for appropriate candidates.

In our database, 63 coaches’ last or current job was at least at a Premier League mid-table level team.

Of these, 44 have managed in the Champions League.

Of these, 30 have a track record of improving underlying performance.

Of these, 18 have consistently outperformed their budget.

Of these, 10 have consistently played attacking and high press football.

Of these, 4 are aged 50 or younger.

This gives you a list of:
Xabi Alonso
Rúben Amorim
Mikel Arteta
Roberto De Zerbi

For all clubs, data can play a critical role in identifying and evaluating suitable coaches. In Liverpool’s case, that’s the easy part – they must now recruit in a seller’s market.
