Jurgen Klopp said Liverpool has always been a club he had interest in and that an offer "would be difficult to turn down."

Klopp left Borussia Dortmund after the 14-15 season and signed his deal with Liverpool shortly after the start of the 15-16 season.

"It's very, very close to how I imagine football -- extremely emotional," said Klopp.

"It's now about developing the club so that it has a natural right to win titles. Everything we can pick up along the way, we will pick up. That's the plan."
