The Robins have won twice in a week to close within two points of the top six, while Leeds have recorded four straight victories, leaving them only a point and two places behind their opponents ahead of the game.
For Holloway, though, there shall be a clear winner. The former Football League boss turned Sky Sports pundit wrote in his predictions column: "Bristol City beating Fulham twice in one week was unbelievable, and the result at the weekend was fantastic.
"I really like the way they're playing with a couple of big monsters at the back and Tammy Abraham up front - who is a fantastic young player.
"Leeds are on a great run as well, I'm delighted for (head coach) Garry Monk as they've been brilliant, but I think their bubble will be burst at Ashton Gate.
Such a result could leave Bristol City, who finished 18th last season, inside the top six places come 10 o'clock Tuesday evening.
While Leeds could also hoist themselves into the play-offs if they upset the apple cart, they are reliant on several other results going in their favour.
The fixture sees Whites summer signing Luke Ayling return to his old stomping ground for the very first time, while Joel Ekstrand, a reported target for Monk in July, could feature for the hosts.
