Liverpool fans' worst nightmare would be for Philippe Coutinho to join Barcelona next summer - or anyone for that matter.
The Brazilian's stock has soared in recent months following a number of fantastic performances in the Premier League, especially so against Arsenal on the opening weekend.
Two goals from Coutinho - one of which an inch-perfect free-kick from 30 yards - saw Liverpool win 4-3 at the Emirates Stadium.
And it's been nothing but positive since then. Between Coutinho, Roberto Firmino, Sadio Mane and Adam Lallana, Liverpool have scored 30 league goals thus far and currently find themselves second in the table.
But such form could work against Jurgen Klopp's men, with Barcelona reportedly interested in signing Coutinho next summer.
That's the overwhelming fear on Merseyside at the moment. Liverpool have a poor track record when it comes to holding on to their best players and history could well repeat itself.
Klopp recently made it clear that Coutinho isn't for sale and that the midfield maestro is perfectly happy with his current surroundings.
"My feeling is he feels really well here, he is happy here and, yeah, we all hope and think his future is here," he said, per the Mirror.
"Sure, if there is a club that can pay double what we pay then who am I to say, 'No, please don't think about the family and the kids and the grandkids and their kids'.
"But I don't know a lot of clubs in the world who are able to do this. The club is not a problem, our owners are not a problem."
Spanish football expert Guillem Balague has now waded in on the transfer talk and, in response to a fan's question on Sky Sports, he explained how Barcelona have "no strategy in place" to sign Coutinho.
Better yet for Liverpool is that the Catalonians are baulking at Coutinho's eye-watering £68 million price tag.
Balague said: "Who has said Philippe Coutinho will be bought by Barcelona?
"There have been a lot of rumours fuelled by Neymar, who would like Coutinho in the side. However, I can tell you there is no strategy in place for Barcelona to sign Coutinho.
"I can tell you the cost of Coutinho is prohibiting Barcelona as it stands at the moment."
Coutinho recently insisted he is happy at Anfield, too.
"I like the position that I'm now playing at Liverpool," he told Sky Sports. "What I like most about it is that I don't have to just stay in one place.
"I have the freedom to move around. The manager is comfortable with me doing it and that's given me the confidence to go and play."
