Barcelona have confirmed Philippe Coutinho is injured and will be sidelined for at least 20 days.
They had signed him for 142 million. The 25 year old has an injury on his right thigh and he is expected to be out of action for some time.
The setback means the former Liverpool man will have his debut pushed back until at least by next month.
Barcelona are currently leading the La Liga table with 48 points, 9 points ahead of Atletico Madrid, who are placed in the second position with 39 points.
