(Reuters) - Barcelona midfielder Ilkay Gundogan said his side had no-one to blame but themselves after they squandered a two-goal advantage and lost 4-1 to Paris St Germain to exit the Champions League 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 went down to 10 men when Ronald Araujo was shown a red card, before PSG took control of the match and secured a comeback win.
