Roma defender Kostas Manolas conceded 'there is no way to stop' Lionel Messi. The La Liga leaders host Roma at the Camp Nou on Wednesday in the Champions League.
But Manolas believed the five-time Balon d'Or winner was immune from being frozen out of a game.
'Guardiola is right when he says there's no way to stop Messi,' the Greek centre-back said.
'Even if you could fix that somehow and maybe block him off, there are 10 others that can hurt you.
'We showed in the group stage that we're a good team. They're favourites, but when you play 11 against 11, you never know.'
