18-year-old Clarke is the talk of the Championship after impressing at Elland Road so far this term.
The youngster netted twice in 13 league games for Leeds and is being chased by a number of top flight clubs.
Manchester United, along with Man City, Tottenham, Southampton and Crystal Palace have all been linked with a move for Clarke.
But when asked about the reported Old Trafford interest, Marcelo Bielsa remained coy over a future move, insisting he didn’t want to talk about the player.
“We haven’t talked about this subject”
“We haven’t talked about this subject,” the Argentinian said.
“I didn’t talk about it with him.
“We have many young players that arrive at the high level.
“The players who start the high competition at the start, we don’t have many players who do that.
“And even less players who stay as high players.
“And the step he is making shows he belongs in the first division and at the highest level.
“We will have conformation of this with time.”
And the player’s agent, Leeds legend Ian Harte, has clarified his client’s future on Twitter.
“Jack will definitely be there,” the former left-back said, in reference to Leeds’ clash with Norwich on February 2.
“And I hope he will be starting!
“I don’t understand why you think he won’t.”
Clarke has been valued at around £12m despite only making his debut earlier this season.
The youngster signed a four-year contract in 2017.
Leeds sit top of the Championship, one point clear of Norwich at present.
