Liverpool locked down boss Klopp to a new deal in the summer running until 2022.
That was despite the German only being appointed at the Anfield club in October 2015.
Liverpool’s title challenge has ground to a halt since the turn of the year and yesterday’s 2-0 defeat to Hull sees them drop 13 points off league leaders Chelsea.

“That would have had a huge impact as they would have been in the Champions League.
“They have probably made a decision with their heart and not their heard by extending the contract by another four years.”
