The transfer deadline passed in England late on Thursday night but Spanish clubs have one more day to complete their summer dealings.
According to The Guardian's deputy news editor Ed Aarons, Barcelona have launched a last-ditch attempt to sign Philippe Coutinho.
The 25-year-old midfielder made his first appearance of the season in Brazil's 2-0 win over Ecuador on Thursday night.
Sidelined with a back injury for Liverpool, Coutinho was deemed fit by the Brazil medical team who believe his health problems in Merseyside have been induced by stress.
The former Inter Milan wonderkid came off the bench to score an excellent goal before producing a rather emotional celebration.
It's no secret that he was hoping to seal a dream move to Barcelona this summer - and there is still time for that to happen, if only Liverpool were to accept one of Barca's generous offers.
Spending big since losing Neymar to PSG, the Catalan giants see Coutinho as the ideal replacement for the ageing Andres Iniesta.
According to The Guardian, the Catalan giants have submitted a final bid of £138m (€150m) for the magical midfielder.
Liverpool are not expected to accept it.
They already splashed out €150m on bringing Ousmane Dembele to the Camp Nou from Borussia Dortmund.
The 20-year-old winger joined the Bundesliga club from Rennes for just €15m last summer.
Coutinho will likely be forced to crack on with Liverpool this season and will hope to emulate Luis Suarez by finally sealing his dream move after the World Cup.
He hasn't featured for Jurgen Klopp this season but could return for next weekend's mouthwatering Premier League fixture away at Manchester City.
Klopp insisted that his relationship with Coutinho remains intact, despite the player pushing for the Liverpool exit door.
"You asked is everything okay between us? I answered with of course. Yes, indeed, absolutely, 100 percent," the German coach told reporters last week.
"Phil can't start tomorrow because on top (of the back problem) he's now ill. If he started training again tomorrow it would take time because he hasn't trained for a long time."
Coutinho's excellent goal-scoring cameo for Brazil on Thursday night suggests there was very little wrong with him.
Unable to bring in any replacements, the Reds will surely reject Barcelona's final bid for their star asset.
