Barcelona coach Luis Enrique is hopeful the injury that forced captain Andres Iniesta off in the second half of Wednesday's Champions League quarter-final first leg against Paris Saint-Germain is nothing serious.

"Andres took what looks like a very hard blow. We will wait to see what the doctors in Barcelona say but it doesn't seem to be anything too serious," said the coach after the game, which the Catalans won 3-1 thanks to a Neymar strike and a Luis Suarez brace.

Iniesta was stretchered off early in the second half and replaced by Xavi Hernandez after appearing to be struck hard in the lower back by the knee of PSG's Javier Pastore just outside his own penalty area.

The second leg will be played at the Camp Nou next Tuesday, April 21.
