Ezequiel Lavezzi has reportedly demanded a move away from Italian club Napoli in the summer.
The Argentine is believed to have had a falling-out with club president Aurelio De Laurentiis.
The president has agreed to the sale, but only if the Naples-based side receive an offer in the region of £30m, according to reports in Italy.
Manchester City, AC Milan and Zenit St Petersburg are all said to be monitoring the situation closely.
