With the new Championship season just days away, Thomas Christiansen may perhaps be looking to use the final training sessions to help make those last key selection decisions before Leeds' trip to Bolton.
Arguably the most challenging decision the Whites boss faces - if he decides to stick with the 4-2-3-1 formation - is who should start in that central attacking midfield role.
Pablo Hernandez is perhaps the safer option. The Spaniard was a regular fixture in that role last term, even when some supporters felt it was time for Garry Monk to look at other options when the 32-year-old was struggling for form.
Though he could go missing for large spells of games, he was extremely productive for Leeds, scoring six times and contributing eight assists in the Championship, and on his day, he seemed impossible to play against.
However, Hernandez has a new teammate to compete against it seems, with summer signing Samu Saiz arguably also in contention to play just behind the sole striker - which will surely be Chris Wood.
Saiz would be something of a surprise selection to start given that he has spent his entire career to date in Spain so would be forgiven for needing some time to adapt to the different demands of the Championship.
Though the 26-year-old would be more of a wildcard, he has won many fans over during pre-season with some of his displays and there appears to be a buzz about what he could bring to the team once he fully settles.
So with that in mind, who do you think Christiansen should select to start in the central attacking midfield role? Vote in our poll below...
