Leeds United take on Sheffield United tomorrow afternoon in what looks set to be a pulsating encounter at the top of the Championship.
The teams sit second and third respectively with the result of this contest having a considerable bearing on the automatic promotion race with just eight games remaining when all is said and done.
Marcelo Bielsa is set to name an unchanged side once more this weekend but could hand Jack Clarke a place on the bench having missed the last six games with illness.
The 19-year-old collapsed by the dugout at the riverside in the meeting with Middlesbrough in last month and has played for the U23s to get up to match fitness.
If the youngster does return to the fold, it is potentially bad news for the Blades after his performance in the reverse fixture back in December.
Clarke was a second-half substitute and played the final 45 minutes of the match at Bramall Lane.
During that time, he had one shot which tested Dean Henderson in the Sheffield United goal, managing 21 touches of the ball, too.
Of those touches, the attacker had one telling moment in the match when he got on the end of a mix-up to slot the ball to Pablo Hernandez to score the only goal of the game.
It was his only key pass of the game, and the most important pass of his ten completed form 13 attempted.
He changed the game with his dynamic attacking play and caused the Blades problems.
Clarke won half his tackles and managed to win the ball in the air once, but his influence was on the ball anticipating a mistake and pouncing on the opportunity.
If he plays against the Blades this weekend, they are in for a tough time considering that he has improved tremendously since that game.
Clarke will look to get at the Sheffield United defenders once more and will anticipate every mistake they make as he looks to make sure lightning strikes twice at Elland Road tomorrow afternoon.
