Ibrahimovic finished the season as PSG's top scorer, netting 30 goals as they won the Ligue 1 title, and the Italian has spoken glowingly about the talents of the Swedish striker.
"I always used to watch him on television and it's an honour to now be playing alongside him," Verratti told Sportitalia.
"Ibrahimovic is a great player who can make the difference all by himself. For me Ibra is the best."
The youngster is also targeting more silverware following last season's title win.
"We had a good season. We won the league title, which was our main objective," he added. "We were delighted and we want to repeat that success this season."
Verratti made 27 appearances for PSG last term.
