The Uruguay forward is still serving the suspension he earned for biting Italy defender Giorgio Chiellini during the World Cup, but is on course to make his Barca debut on the weekend of October 25.
"It's special that he chose to come here [from Liverpool]," Messi told Fox Sports Magazine. "We will be stronger as a team with him. We will have a lot more variety."
Suarez, who scored twice for Barcelona's B team earlier this week, joined the La Liga giants from Liverpool over the summer in a deal that was reportedly worth £75m.
