Manchester United looked into signing former Arsenal goalkeeper Wojciech Szczesny before David De Gea signed his new deal.
Old Trafford boss Ole Gunnar Solskjaer was concerned that De Gea would reject a new contract so wanted a back-up option and approached Juventus for their No1.
Juve have now moved to tie up a new deal for Szczesny, with his current contract set to end in 2021.
There are fears in Italy that the Poland stopper could be lured away if he is allowed to enter the final year of his contract.
De Gea, 28, agreed a new four-year contract at United in September.
The Spaniard will remain at the club until 2023.
The deal had been on the table most of the summer and delays at De Gea’s end convinced Old Trafford chiefs he was not going to sign.
Tottenham’s Hugo Lloris and Everton’s Jordan Pickford were among those linked with a move to United to replace De Gea.
But the Spaniard’s decision to finally put pen to paper on a £350,000-a-week deal ended United’s interest in signing a back-up stopper.
De Gea had less than 12 months remaining on his contract.
Szczesny moved to Serie A in 2016 after losing his spot at Arsenal to Petr Cech.
The 29-year-old had been on loan at Roma during the 2016/17 campaign.
He joined Juventus in 2017 for £10million.
Szczesny made 17 league appearances for the Old Lady in the 2017/18 season, winning the title in his first season with the club.
The Pole also helped them win the title last season, making 41 appearances.
