Philippe Coutinho and Mamadou Sakho have both been guilty of causing Jurgen Klopp grief.

Both have rocked the boat and let down a manager who demands that every one of his players always puts the team’s interests before his own.

However, their fate with transfer deadline day approaching next Thursday will be very different. One will be quickly forgiven and welcomed back with open arms, while the other is shown the exit door.

Coutinho will be reintegrated into the squad after the international break. Klopp will seek to draw a line under the Brazilian’s persistent and unsuccessful attempts to force a move to Barcelona this summer.

But for Sakho, this is the end of the road. His four-year stay at Anfield is over. Crystal Palace and West Brom are set to battle it out for him, with Liverpool prepared to negotiate on the structure of a deal that meets their £30million valuation.

Sakho hasn’t kicked a ball in anger for the Reds since April 2016 when he scored in the derby rout of Everton, but his cult hero status among a section of the club’s fans remains unbroken.

When Klopp declared this week that he doesn’t bear a grudge against Coutinho, some cried double standards and demanded that Sakho was afforded the same shot at redemption. In truth the two situations are incomparable.

Coutinho was selfish to submit a transfer request on the eve of the new Premier League season when he had already been told by both Klopp and FSG president Mike Gordon that he was going nowhere.

His desire to sign for Barcelona was understandable, but less so was his refusal to accept the Reds’ stance given that he penned a five-year contract with no release clause seven months ago and had eulogised about his life on Merseyside.

Coutinho might not have been responsible for some of the unseemly antics from his camp with claims about his relationship with Klopp breaking down, but he could have stopped the whole saga dragging on as long as it has.

Whereas Coutinho kicked up a fuss after his head was turned by the bright lights of Barca, Sakho has no such excuse for finding himself in the doghouse.

The fact is the writing was on the wall for Sakho when he was sent home in disgrace from Liverpool’s pre-season tour of America 13 months ago. Late for the team flight, late for a team meal and failing to turn up to treatment sessions, he riled the manager with his bad attitude and lack of professionalism.

Sakho was already on thin ice after the doping row with UEFA. He was eventually cleared of taking a banned substance but had broken club rules by using a fat burner without Liverpool’s blessing.

He ignored Klopp’s advice to go out on loan a year ago and then unwisely embarked on a late night Snapchat rant about being frozen out. He did well on loan at Palace in the closing months of last term but there was never any chance of Klopp holding out an olive branch.

Talent also comes into the mix because football doesn’t operate to a strict moral code.

If Klopp really thought that Sakho was the answer to Liverpool’s defensive frailties then that relationship would have been repaired.

The better you are, the more you’ll be forgiven. Just look at Luis Suarez’s charge sheet during his time at Anfield.

Some fans will argue that once Coutinho said he didn’t want to play for the club again he should have been sold.

But Klopp doesn’t share that point of view. He will put aside his own personal disappointment at Coutinho’s conduct because he knows what a difference he can make to the side this season. He also knows that Coutinho remains a popular figure in the dressing room.

Whereas Coutinho is worth fighting for, Klopp has long since concluded that Sakho simply isn’t worth all the hassle.
