Leeds chasing Rodrigo de Paul, AC Milan and Liverpool also interested
The 26-year-old Argentina midfielder has experienced playing in his native country and Spain before moving to Italy in 2016, scoring 34 times in 182 appearances for Udinese.
The report claims that Udinese have put a €40million (£34.5million) price tag on De Paul, which would make him Leeds' record signing if he were to go to Elland Road.
Bertrand on Leicester's radar
After seven years as a Saints player, the club have confirmed that Bertrand will leave St. Mary's over the summer, with Brendan Rodgers hoping to bolster his options at left-back.
31-year-old Bertrand, capped 19 times by England, will be likely to be in demand as a solid option as a free agent at the end of the season.
Bielsa expected to pen new Leeds deal
Bielsa has only signed one-year deals in his time at Leeds so far, but a two-year contract is said to have been tabled to keep the Argentine at the club.
The Leeds boss had been an outside bet to become the new Tottenham manager, with Bielsa currently priced at 25/1 to take on the Spurs role - although a new contract at Elland Road would put those rumours to bed, which he is expected to sign following the conclusion of the season.
