The Italy starlet believes the mere presence of the Sweden international in the Paris Saint-Germain team gives the side a huge amount of belief
PSG won the 2012-13 title with a 12-point advantage over second-placed Olympique de Marseille, with the former AC Milan striker playing a starring role in their success, netting 30 goals in 34 games in the French top flight.
Verratti believes the ex-Barcelona man gives much more than a goal threat to the team, however, claiming he gives the entire squad a sense of belief whenever he takes to the pitch.
"I am forced to say Ibrahimovic," the 20-year-old told the club's official website when asked who is les Parisiens' most important player.
"He's a true leader, he has an incredible impact on the team. When you start a match with him, we know that everything will go smoothly."
The youngster is also impressed by the Sweden striker's original way of celebrating each of his strikes.
"He has a unique way of celebrating his goals," Verratti added. "He loves to jump and explode with joy. You can feel the satisfaction of a player who has accomplished what fuels him."
