Tancredi Palmeri claims Marcelo Bielsa wants to sign the 20-year-old defensive midfielder this summer and pair him with Kalvin Phillips.
Luis only made his senior debut last year but has quickly emerged as one of Portugal’s top prospects.
AC Milan and Real Betis are said to be very keen on snapping him up.
But it looks like Leeds are in pole position after they sealed their Premier League return by winning the Championship title.
Bielsa guided them back to England’s top flight in just his second season at the helm.
And the veteran tactician’s next task is to reinforce his squad with players capable of beating the drop.
Luis would be a fine start, and Leeds would also like to add free agent Edinson Cavani too.
However, the former Paris Saint-Germain striker is instead expected to sign for Benfica – the club Leeds are currently talking to about Luis.
SunSport can also exclusively reveal Bielsa wants to strike a £15million deal for Tottenham defender Juan Foyth.
He could be on his way to Elland Road regardless of Ben White’s future at the club.
Leeds have also expressed an interest in highly-rated young striker Jonathan David, with his club Gent confirming an offer from Bielsa.
The Argentine could also move for compatriot Thiago Almada, a central playmaker who is apparently keen on playing for Bielsa and is even prepared to snub Manchester United to make a move happen.
