Leeds United defender Liam Cooper has been out of action since the start of December.
Cooper has been out of action since the start of December, after picking up an injury in Leeds’ match against Sheffield United.
The commanding centre-back has now been out for Leeds’ last six league matches and he has been missed.
Leeds have kept just one clean sheet during Cooper’s absence, but the Scot is now in full training again.
And Bielsa has suggested that he will come straight back into Leeds’ team now he has proven his fitness.
“I went to see the game on Monday versus Hull City. He played an hour. He is in good condition to come back to the team,” Bielsa said.
“He has a very good first pass, he is good with the aerial balls, he is our captain and he deserves to be our captain.
“When he’s inside the team he makes the team stronger.”
Leeds’ next game comes on Friday evening, when they take on Derby County at Elland Road.
Leeds have lost their last three matches on the spin, so there is some pressure on Bielsa’s men to get a result.
If Leeds do manage to pick up a victory then they will move five points clear at the top of the Championship table, ahead of this weekend’s matches.
