Palermo president Maurizio Zamparini says Paulo Dybala will be sold this month

Palermo president Maurizio Zamparini has told Paulo Dybala's suitors to act quickly in order to secure the services of the coveted Argentinian forward as the club will agreed his departure by the end of April.

Having scored 13 goals and provided eight assists in 29 Serie A appearances this season, the 21-year-old has been heavily linked with some of the biggest clubs around Europe, including Barcelona, Juventus, Arsenal, Manchester City and Manchester United.

The outspoken chief has initiated a public auction among them in recent months in order to get most for Dybala's services, placing a minimum €40m (£29m, $43m) price tag on his signature while saying the forward "is going to be the Lionel Messi of the future".

Earlier last month Zamparini revealed he had already received two lucrative offers from Juventus and the Gunners to secure his services.

Arsene Wenger quickly denied having made any offer during a press conference while saying the Gunners are not interested.

Nevertheless, just days later Dybala's agent, Gustavo Mascardi, confirmed that at least one unnamed English club are monitoring the situation.

"There are so many good offers, the boy may have an important future," Mascardi told Gazzetta TV. "There are few talented players like him. Abroad, there are major deals, in particular with an English club. In Italy, there are two or three interested sides."

And amid reports suggesting Louis van Gaal's side could be the one involved in the battle for Dybala, Zamparini has now claimed that a deal to sell the Argentinian will be agreed "by the end of April" while adding that Juventus and Roma are in pole position.

"Dybala will be sold by the end of April," Calciomercato reports Zamparini as saying.

"Along with Juventus, Roma are the team most interested in my lad from our league. Dybala would help them for sure, and Roma don't have money problems.

"But then there are foreign teams. [Dybala's agent Pierpaolo] Triulzi, with my blessing, is going between Paris and London getting the offers, and then we'll evaluate them together.

"Also, we'll meet with [Juventus general manager Giuseppe] Marotta again. I wonder if he wants to raise his offer..."
