Patrice Evra ranks Celtic as one of the best places he's played at - and their famous anthem outperforms the same song at Liverpool.
The former left-back won the Champions League with Manchester United in 2008 and has played at Parkhead, which is renowned for its passionate atmosphere on European nights.
Evra featured briefly for Sir Alex Ferguson's side as the Hoops famously downed United 1-0 thanks to a Shunsuke Nakamura free-kick in 2006.
Noise made in Glasgow's east-end is hard to match and even Liverpool - who lost the major European final 1-0 to Real Madrid on Saturday - can't hold a candle to it at Anfield.
Both clubs sing 'You'll Never Walk Alone' but Evra says the Parkhead version blows the Merseyside equivalent out the water.
When asked about the best atmosphere, he said on YouTube: "I think in Turkey, Galatasaray and Besiktas was amazing.
"But you know what the atmosphere I also enjoyed was Celtic. It was just amazing.
"We played Celtic at Manchester United in the Champions League.
"The atmosphere was electric. This is where you get the real 'You'll Never Walk Alone', the real one."
Ange Postecoglou's side return to the top table of European football this autumn after Premiership title glory earlier this month sealed a £40 million European jackpot and at least three memorable Parkhead nights.
