Good news if true.
Sprain in internal lateral ligament of the right knee.
official barca statement.
Out for 3 weeks..
Not sure about this. Could be he just feared he got reinjured again at first but he looked uncomfortable in 2nd ET and his team mates also avoided to pass the ball to him when not needed to not get him into tough situations. Luckily Sevilla was also down a man and they didn't put all that much pressure on us in last minutes. FDJ also stayed back to help him out.
You were right. Out for three weeks.
Don't doubt my reliability.
