Athletic Bilbao striker Fernando Llorente has admitted that Marcelo Bielsa is a very demanding coach.
The 56-year-old has earned plaudits from across the footballing world after his side knocked Manchester United out of the Europa League earlier this week.
Despite Bielsa's intense approach, Llorente believes that he gets the best out of his players.
"He is a very demanding coach and he gets the most out of every player, to the point where it can overwhelm you," Llorente told Ole.
"In the end, you know it is for your own good, and for the good of the team.
"He is is doing a magnificent job here. He is very important, one of the keys to the success of the team."
Bielsa recently gave nothing away over his future at Bilbao following reports that he is in the frame to take over at Inter Milan.
