U23 coach Mascherano who once played alongside Messi for Barcelona and Argentina, has told TyC Sports of calling upon legendary figures: “One understands the times for the senior national team: there's the Copa America, it's not easy. For that reason we have to be cautious, obviously we're going to talk about everything. You know my relationship with both Angel and Leo. We're friends, we have a spectacular relationship. Me as a manager, obviously I have the obligation to invite them but one also understands that they have other commitments. It will also depend on that, it's not so simple. Equally there is time to talk about it.”
