Philippe Coutinho only joined Barcelona from Liverpool just over a year ago, yet his future at the club is already in doubt.

Poor performance after poor performance from the 26-year-old this season has sparked suggestions Barca could look to cash in this summer.

Manchester United are reportedly interested, while a lot of Liverpool fans have said they would take him back in a heartbeat.

Eight goals in all competitions is a far cry from the form that earned Coutinho a £142m move to Barcelona in the first place.

He's looked sapped of confidence in recent months as a result of playing so badly, time spent on the bench and some rather harsh reviews from the Spanish press.

Indeed, Lluis Mascaro of Catalan newspaper Sport recently said that nothing is working for Coutinho and there are no excuses for his form.

"Coutinho has been at Barca for a year now and is only getting worse," Mascaro wrote. "Worse and worse. Unjustifiable for a player that cost €150m.

"The most expensive signing in the history of the club. Not even [Lionel] Messi's support, [Ernesto] Valverde's therapy and [Josep Maria] Bartomeu's advice can fix him.

"Nothing is working. There is no excuse. Or forgiveness."

In response to all the speculation about his future at Barcelona, Coutinho said in January that he doesn't know what will happen.

"Nobody knows what will happen in the future," said the Brazilian. "All I have in my head right now is to work hard."

Time is of the essence for Coutinho to save his Barcelona career, not to mention his market value, which has plummeted since he moved to the Camp Nou.

According to the number-crunching football website TransfrMarkt, Coutinho is currently valued at just £90m - £52m less than what Barcelona paid for him in January 2018.

Luis Suarez's market value has also dropped over the past year at Barca - he's now worth £54m - but that's largely due to his age, whereas Coutinho is only 26.

If Coutinho's poor form continues for the rest of the season and Barcelona decide to sell this summer, it looks like they would make a huge loss. Liverpool, meanwhile, struck a sweet deal.

No pressure, Philippe.
