Roma chief Monchi has dismissed claims Barcelona are a one man team.
Roma meet Barca in the Champions League quarterfinals.
And former Sevilla sports director Monchi said: "Having Messi or not conditions a team, but it does not seem fair to me to say that Barça becomes less a team without Lionel Messi.
"He makes differences and turns Barça into an even more unbeatable team, but there are players around him who make it a very hard team to beat."
