In 20 appearances, Hojlund has scored nine goals and three goals under manager Antonio Conte, who certainly knows how to get the best out of the Danish international.
Napoli snapped Hojlund up on a season-long loan for around €6m, with a €44m option to buy that is set to be triggered in what could be one of the biggest bargains of the summer.
Speaking to Corriere dello Sport, Manna was asked about the signing of Hojlund and if he could become a permanent signing in the near future.
“We did everything we could to sign him. There were more storied clubs interested, but his will was crucial, and we are proud of it.
“We had no doubts. Rasmus is decisive in terms of numbers, but also in how he understands the coach’s input. This makes a difference.
“There’s an option to buy and an obligation to buy if we qualify for the Champions League.
“The player considers himself a Napoli player, and the same goes for us. This is extremely important.”
The reporter asked if a permanent move was just a “formality,” and Manna replied: “As of today, I think so.”
Napoli have already found success with Scott McTominay who has shined away from United, winning the Serie A player of the year last season.
The midfielder and Hojlund were team-mates for just a season at Old Trafford before and it looks very likely they could be together for the forseeable future.
