Liverpool fans have already felt the disappointment of seeing their club lose a key player more than once over the past few years, and could face yet more dismay if their current form fails to improve.
Rumours are rife that Spanish and European champions Barcelona are interested in creative midfielder Philippe Coutinho, who has matured into arguably one of the best playmakers in the Premier League since joining Liverpool.
The little Brazilian is a key part of manager Brendan Rodgers' team and there are fears amongst the Liverpool faithful that should their side fail to achieve their goals of winning a trophy or making it to the top four this season, Coutinho could emulate the departures of former integral stars Luis Suarez and Raheem Sterling.

Despite starting the season somewhat strongly, going three games unbeaten, their form has since declined and are now four games without a win in all competitions - form that must change if the Reds are to challenge for some silverware and indeed a place in the top four that will help keep their stars and attract quality.
Coutinho has certainly shown his quality at Liverpool, impressing not only his fans but his team-mates since his arrival in 2013, with former Red Steven Gerrard a particular fan of the 23-year-old.
Gerrard mentioned Coutinho in his new book, 'My Story', revealing fears that the Brazilian could become the next Liverpool player to leave the club for a European giant.
He said, according to the Mirror: "I also know that the Spanish giants, Barcelona and Real Madrid, will come looking for Philippe in a few more seasons, just like they did with Luis.
"And that's when it will get tricky for Liverpool because the lure to go to one or two of those clubs is so strong for any South American or Spanish player."
The two Spanish powerhouses clubs are renowned for buying world-class players and with Gerrard thinking so highly of him, it would be fair to say that Coutinho falls into that bracket.
Add to that the fact that Barcelona star Neymar said: "I see many Brazilian players with quality today. But one I like and think could play here is Coutinho. He has the style of Barcelona," and it becomes glaringly obvious that Coutinho can do better than Merseyside.
Liverpool fans will be hoping that this remains nothing more than just another transfer rumour, but it is crucial that Brendan Rodgers' men start winning quickly or else this rumour may become a reality.
