The Barcelona captain has been in brilliant form again this season and has scored six goals in just four Champions League appearances.
Genesio says his team must defend as a unit and pressurise the Argentine if they are to neutralise his threat.
“The anti-Messi plan will be rather collective, where we will all have to respond. We will have to strengthen the midfield and the pressure around Messi,” he said.
“If you do individual marking to a man like him, at some point it will make a difference. And then, there is another aspect. We must defend well, when we do not have possession of the ball.”
