Barcelona midfielder Xavi still holds a grudge against Chelsea over their courageous Champions League triumph in 2012.
Chelsea knocked out Barca in the semis on the way to beating Bayern Munich on their own turf in the final.
But bitter Xavi can't let go, telling the Sunday Telegraph: "Chelsea won the Champions League but by my reckoning, without playing good football.
"They did it legitimately, but I think they were very lucky.
"When Bayern beat us, they outplayed us, and there was nothing we could say about it. The night we got knocked out by Chelsea was a real, real shame. We were the better team, we went into the game in the right shape and right frame of mind, we were winning 2-0, we even had an extra man! We should have killed the game off. It was an awful sensation, it was unjust."
