2017/18 in England will forever be embedded into the minds of Liverpool fans, and perhaps some football fans, as the season of Mohamed Salah. 

The Egyptian was bought to Liverpool for a sum of 36.5 million pounds just before the season had started.

By the time it had ended, he was the Premier League Golden Boot winner, the record breaker of most goals scored in a debut season and in an overall 38-game season, PFA Player's Player of the Year, PFA Fan's Player of the Year, Football Wirters' Player of the Year and Premier League Player of the Year among numerous other accolades.

No wonder it was such a memorable season.

However, Salah wasn't the only star in the 2017/18 Liverpool side, at least for the first half of the season. 

Philippe Coutinho unveiled at Anfield

Liverpool's 2013 signing from Inter Milan, Philippe Coutinho, had hit his prime and was tearing apart Premier League defenses along with Salah, Roberto Firmino and Sadio Mané.

They were affectionately called the 'Fab Four" by Liverpool fans, after the iconic Liverpool based musical band, "The Beatles".

The Brazilian had seven goals and six assists in 14 games League games he had played for Liverpool in his last season. 

He had also scored five goals and given out two assists in the six Champions League group stage matches he and participated in.

Naturally, he attracted interest and soon La Liga's Barcelona were bidding for Coutinho, who was equally eager to secure almost every South American footballer's dream, to play for FC Barcelona.

Liverpool were reluctant to let him go, obviously, as he was their best attacker at that point. 

However, Coutinho was determined to leave, even paying some of his 142 million pound transfer fees to Barcelona himself out of his own pockets, and come February, Phillipe Coutinho was playing in Camp Nou.

However, the "Little Magician" failed to achieve his dream completely. 

He was a marquee signing for the Catalan club but, unfortunately for him, he was anything but that over the course of the next four years.

In the 90 appearances he has made in two and a half seasons with the Blaugrana, he has scored 23 times and assisted 14 times. 

Although not a bad overall statistic, it was evident how underwhelming he has been since his big move from England.

In his 2019/20 loan spell at Bayern Munich, he had eight goals and six assists in 23 games. 

Ironically, he had scored twice and assisted once in his parent club's 8-2 demolition by the Bavarians in the 19/20 Champions League Quarter Finals.

His wish to win the Big Ears with Barcelona was thwarted in 2018, 2019, and 2021 as well, at the hands of Roma, Liverpool themselves, and PSG. 

He did win it, and the treble, in Germany though, with Bayern Munich. 

Now, injured since December of 2020, Barcelona are desperate to get rid of Coutinho, mostly to clear their inflated wage bill, and Liverpool have been said to be interested to take back their former star.

Barcelona are now willing to sell Coutinho for an alleged sum of 20m euros, a player they had signed for about seven times that price.

Some news outlets, albeit not that reliable, have reported that Liverpool are considering bringing back the Brazilian to Anfield now that his price tag has significantly reduced and they are in need of a backup attacker.

However, Diario SPORT, a Spanish news source, have shut down all these rumours and have reported that Jurgen Klopp has "blocked" the move. 

The German has apparently quickly closed any possibility of buying back his former player, and never was invested in the idea in the same place.

Most probably, it is the best for the club as well. 

Coutinho is 29 years-old now, too old for a club who usually signs young players unless there are exceptions (for example, Thiago, last summer). 

He has also lost the magic he once displayed every time he stepped on the pitch, now a shadow of his past self.

Klopp had reportedly told Coutinho, "Stay here, and they will build a statue in your honour. Go somewhere else, to Barcelona, to Bayern Munich, to Real Madrid, and you will be just another player. Here you can be something more." 

In the current circumstance, it can't be more true. 

From one of the best players in the Premier League, he is now been reduced to a fringe player.

Liverpool will always gratefully remember the performances Coutinho had put out for their club for five years, but they will always remember how he left them in a middle of a season when they needed him.

He could have been something more if he stayed, but that is now only something to mull over.
