Leeds will sign Illan Meslier permanently for £6million at the end of the season if they win promotion to the Premier League.
Meslier, 20, has impressed during his loan spell at Elland Road from French Ligue 2 side Lorient and Marcelo Bielsa believes he is one of the best young goalkeepers in Europe.
The Frenchman has kept two clean sheets deputising for the suspended Kiko Casilla and Leeds will active his £6million buy-out clause if they go up from the Championship.
The France Under-20 international also stood out on his Leeds debut in their FA Cup defeat to Arsenal in January.
Leeds fans have taken to Meslier and have urged the club to sign him permanently.
Meslier, who was spotted by Leeds goalkeeping coach Marcos Abad, has been with his home town club Lorient since he was six and has represented France at every level up to the Under-20s.
He received his first Under-21 call-up in November, although he has yet to be capped at that level.
Leeds were impressed with Meslier before he made his senior debut and he saved three penalties for their Under-23s.
Meanwhile Meslier's Leeds teammate Kalvin Phillips has lifted the lid on his frustrations in dealing with boss Bielsa.
“He’s never completely satisfied,” said Phillips. “He’s always saying I can improve.
“That can be frustrating when you think you’ve played well, but those are the standards he sets.”
Bielsa was the orchestrator behind the change in Phillips' playing position - something which took the midfielder aback.
“I was surprised at first,” he told FourFourTwo. “The season before he arrived, I’d scored seven goals, so I was a bit confused and disappointed when he spoke to me.
“I could hardly say no, though, could I, especially given his track record of improving players?
“He saw something in me and offered to teach me how to play a different role.”
