Manchester United have registered their interest in signing Palermo striker Paulo Dybala but have been told to wait until the summer transfer window in order to sign the Argentine youngster, with Arsenal also among his suitors.
Dybala has netted nine Serie A goals this season and is on the radar of a host of Europe's biggest clubs.
The ex-Instituto forward has been compared to the likes of Sergio Aguero and Javier Pastore and is valued at €40m by Palermo, who are seemingly consigned to him leaving the club at the end of the current campaign.
Arsenal are among the clubs monitoring Dybala, with the player having described the Gunners' interest as "incredible" but United are the latest side to enter the race for the player after Zamparini admitted the Old Trafford club have been in contact over his availability.
"Dybala is worth over €40m [£31m] but I won't sell him until June," Zamparini told Radio Due.
"Many foreign clubs asked after him, including Manchester United. I told the English side that he is not for sale right now, but we can talk about it again in six months. In my view, he is the best striker in Europe at the moment."
United's recent interest in Dybala is likely linked to the future of Radamel Falcao, whose loan spell at the club is unlikely to be extended after an injury-ravaged first half of the season which has yielded just three goals.
With Robin van Persie's form and fitness also on the wane, United could make signing a new forward a priority in the summer transfer window, however the Italian league hitman appears to already have his heart set on a move to Arsenal.
"Things are going well, but I cannot relax," he told Goal.com. "I have to keep going and always be focused. All the rumours about my future are the result of my hard work and I have to keep doing things the same way.
"It's an incredible feeling to be linked with clubs like Borussia Dortmund, Inter, Barcelona and Arsenal. All players dream of joining a big club and playing with the best. You always try to give your all and reach the top. My goal is to work hard and reach the top."
