Di Natale, who scored 209 Serie A goals and played until he was 38, made his views plain in an interview with La Gazzetta dello Sport.
"I would like to see Lewandowski in Italy next year. I stopped at 38, he is 37 and he is a super striker. In Serie A he would score for another two seasons playing with a cigarette in his mouth."
His conviction is backed by what Lewandowski has already produced this season. The Barcelona forward has scored 17 goals across all competitions despite starting fewer than 40 per cent of La Liga matches, having been regularly overlooked by coach Hansi Flick in favour of younger options. His contract expires on 30 June, and a reduced renewal offer from Barcelona has not met his expectations.
Juventus are understood to have moved furthest in negotiations. Agent Pini Zahavi has held preliminary talks with the Turin club's hierarchy, with Juventus prepared to offer a one-year deal worth approximately €6 million — a significant reduction from his current Barcelona salary but a package they believe could be structured to suit both parties over two years. Transfer expert Fabrizio Romano confirmed Zahavi is preparing a visit to Italy to progress discussions.
Milan are also monitoring the situation but are more cautious, divided internally over the financial commitment given Lewandowski's age. The club's primary striking target remains Alexander Sørloth of Atletico Madrid. Lewandowski's own preference, however, is understood to be a project that offers him Champions League football and a leading role — not a squad position.
The key variable for both clubs is the outcome of their respective qualification campaigns. Juventus are pushing for a top-four finish in Serie A. Confirmation of that would, according to reports from Italy, trigger a more decisive approach for Lewandowski.
Di Natale's advice was straightforward: two years, no hesitation.
