Barcelona's 2009/10 Champions League semi-final loss to Inter still hurts for Bojan Krkic, who scored a goal that should have been the winner.
With Barcelona 3-2 down on aggregate, he fired in an effort in stoppage time that would have seen the Catalan team progress on away goals, but it was ruled out by Frank De Bleeckere, the referee, for a non-existent handball by Yaya Toure.
"When the ball went in I was so happy," Bojan explained to MARCA, remembering that spring evening in 2010.
"But then I realised that something was going on.
"The sense around the stadium and the players wasn't an enthusiastic one, which was when I realised that they'd ruled it out.
"It was key because it would have completed the comeback and put us in the Champions League final, a very special one given that it was to be held at the Estadio Santiago Bernabeu."
Had the goal been given, Bojan's whole career path might have been different.
Yet the player himself doesn't want to dwell on this too much.
"Sometimes I do ask myself what would have happened had it been a goal," he said.
"However, I've never gone so far as to ask how my life would be.
"It just didn't happen because it wasn't supposed to happen."
Bojan is currently playing for Stoke City in the English Championship.
