Surrounded by stewards and facing the wrath of a three-deep line of seething home fans, Neymar was being escorted out of Celtic Park just as Neil Lennon launched his criticism of the Barcelona winger.
"I don't think Neymar does himself any favors by the way he behaves at times,'' the Celtic manager said. "Our supporters are very respectful of great players. (Barcelona playmaker Andres) Iniesta walks off tonight to a standing ovation from the Celtic support. While Neymar, he gets booed every time he touches the ball.''
As Lennon spoke calmly, despite his anger inside at a post-match news conference, his words were quickly drowned out as the jeers of Celtic supporters toward Neymar grew louder and louder.
The Brazil international was one of the central figures in a game-changing incident in the 59th minute of Barcelona's 1-0 win over Celtic in the Champions League on Tuesday.
With the game poised at 0-0, Neymar was tugged back and then bundled over by Celtic captain Scott Brown as Barca launched a quick counter-attack. Brown then went further by flailing his boot at the arm of Neymar, who fell and rolled around on the ground in apparent agony and holding his back.
