The Reds midfielder played a key role in Liverpool FC’s Champions League success last term to win his first major trophy since his move to Anfield.
Wijnaldum was left out of the Liverpool FC starting XI for the second leg of their Champions League semi-final after a 3-0 loss at FC Barcelona.
The Netherlands international came off the bench at half-time to replace Scotland defender Andy Robertson at Anfield.
Wijnaldum had an immediate impact after the Dutch playmaker scored two quick-fire goals to level the Champions League tie on aggregate.
Klopp started Wijnaldum in the Liverpool FC team for their 2-0 victory over Tottenham Hotspur in the Champions League final in Madrid back in June.
Wijnaldum has now opened up about his relationship with Klopp at Liverpool FC.
“With the manager it is more or less hate and love,” Klopp is quoted as saying by the Daily Star.
“I am sure Klopp has the best interests at heart with every player in the squad.
“But sometimes as a player, you are so intensely involved in a match and then the manager is still chasing you.
“Then you just boil over sometimes – and in my case, I do get angry with him.
“I still don’t know if what happened against Barcelona was his real plan. But that night I was so, so angry and so disappointed that he did not start me.
“Looking back, we can all say things worked out all right. We will never know how things would have gone if the manager had started me.”
Liverpool FC finished in second place in the Premier League table last term after the Reds ended up a point adrift of champions Manchester City.
The Merseyside outfit have won their opening four Premier League games this season to leave the Reds at the top of the top-flight table.
Liverpool FC will return to Premier League action with a home clash against Newcastle United at Anfield on Saturday afternoon.
