BARCELONA, Spain (Reuters) - Barcelona manager Xavi Hernandez berated the referee and said his performance cost Barcelona a chance to fight for a place in the Champions League semi-finals after they lost 4-1 to Paris St Germain and were knocked out of the competition on Tuesday.

After winning 3-2 in Paris and taking a 1-0 lead with an early Raphinha goal in the quarter-final second leg, Barca were down to 10 men just before the half-hour after last man Ronald Araujo was shown a red card for a foul on Bradley Barcola.
