Manchester United favourite Nemanja Vidic has revealed Celtic fans were the only ones to intimidate him during his career as a player.

Serbian hero Vidic recalled the "fire breathing" supporters who can terrify visiting stars.

Widely regarded as one of this generation's biggest and meanest defenders, not much - you would imagine - would worry the former centre-half who learned the ropes at Red Star Belgrade.

But the blood-pumping atmosphere inside Celtic Park during the 37-year-old's time at Old Trafford is the closest Vidic got to being fearful as he visited twice in 2006 and again in 2008.

Chatting with The Athletic about playing in Italy for his national side, Vidic said: "They were in Naples, which had a reputation for being loud and intimidating, but when you have played at Red Star you don't really get intimidated.

"Maybe only at Celtic Park for the first 10 minutes of a game when the fans breathe fire towards the players.

"I loved playing at Celtic and felt like it was my mentality that I had grown up with."

Vidic also hailed ex-Italy striker Filippo Inzaghi as one of the most difficult players he ever played against due to his movement inside the area.
