Barcelona are reportedly favored by Gianluigi Donnarumma ahead of Paris Saint-Germain, while Juventus are likely to keep Szczesny under Massimiliano Allegri.
The goalkeeper is a free agent after failing to agree on a new deal with the Rossoneri.
Mino Raiola is working to find a club that pay at least 10 million euros per season, but this isn't easy in the current financial situation.
According to Sky Sport Italia, Barcelona are currently the main chance to sign the 22-year-old, and even if Marc-Andre ter Stegen stays at the Camp Nou, they are ready to sign Donnarumma.
PSG keep an eye on the situation but recently extended their contract with Keylor Navas.
Juventus were expected to sign Donnarumma, but Allegri's return has changed the situation. It should also be noted that the Polish goalkeeper's contract is valid until 2024.
