The German's first full season at Anfield has seen the side really gel together and produce some impressive performances, and they look like mounting a genuine title challenge.
Keane thinks that is all down to the Klopp factor.
"Liverpool under Klopp have been great," he told Press Association Sport.
"I love watching him on the sideline, I love his interviews and I love the way he interacts with the players.
"He is exactly what the Premier League needed and exactly what Liverpool needed.
"Look at how he's got the best out of players. (Sadio) Mane from Southampton has been exceptional, Firmino has been brilliant as have (Adam) Lallana and (Jordan) Henderson.
"He is getting the best out of players and you can see the players have bought into everything he is trying to do.
"They are the most exciting team at the moment to watch."
