C.Ronaldo and Lionel Messi finally comes to agreement after 15-year rivalry on one thing.

Both stars have played at iconic stadiums like Wembley, San Siro, and Nou Camp, but Celtic Park stands out.

Other grounds pale in comparison, as Barcelona legend Xavi said in 2015;

"The grounds of Liverpool and Manchester United are good and the hostile feeling of playing against Real Madrid in the Bernabeu is also excellent, but the atmosphere against Celtic was the best."

Messi and Ronaldo share similar admiration for Celtic stadium

Lionel Messi also shared his experience:

"I've been fortunate to play in some great stadiums in Europe with Barcelona, but none compare to Celtic. The atmosphere their fans create makes it a very special European night of football."

Cristiano Ronaldo, who faced Celtic three times, losing once in 2007, shares similar sentiments:

"The Celtic fans are incredible. It is always great to play there."

Other legends, like Gigi Buffon and Paolo Maldini, have also lauded the atmosphere, especially the fans who never stop singing and cheering their team on.

Celtic may not be the best team in Europe, but their 60,000-capacity stadium will remain iconic.
