Philippe Coutinho boosted his already impressive reputation this week whilst on international duty with Brazil.
The 24-year-old Liverpool star scored a sensational goal in his country's 3-0 win over Argentina before playing his part in another crucial win on Tuesday night, this time against Peru.
And, just when Liverpool fans thought the worst that was to come out of Coutinho's Brazil heroics was hearing him being linked with a move to Barcelona, the Liverpool Echo revealed on Thursday afternoon that his exploits may have come at a cost.

The Merseyside paper, in an article by their Liverpool FC reporter James Pearce, revealed that Coutinho had been sent for a scan at the city's Spire Hospital on Thursday amidst fears that he had returned from Brazil duty with an injury.
Although there are no further details as to exactly what issue Liverpool were so keen for their Brazilian star to get seen to, there is already speculation that Klopp could be without arguably his most influential player for this weekend's game against Southampton.

As you can imagine given Coutinho's form so far this season, the news hasn't exactly gone down well with Liverpool fans on social media.
Especially when you add in the fact that Adam Lallana is already all but certain to miss the fixture after picking up an injury whilst playing for England against Spain on Tuesday night.

Although, in a sign of the times as Liverpool battle at the top of the Premier League, there are some fans who are confident that the current first-team squad is deep enough to cope without both Coutinho and Lallana.
It remains to be seen just whether Coutinho - fresh off the back of 170 minutes of action for Brazil and a flight half way across the world - is ready to play his part for Liverpool at the weekend.
If he isn't then Gini Wijnaldum and Daniel Sturridge are expected to come into the starting lineup in place of both the Brazilian and Lallana.
Although they would never wish to be without a player of Coutinho's quality, if he were to be out for weeks rather than days, then Liverpool fans would probably rather it be now than further down the line.
With winnable fixtures against Sunderland, Bournemouth, West Ham and Middlesbrough to come over the next few weeks, Liverpool could cope if the worst were to be announced.
