United head coach Marcelo Bielsa had two main selection concerns ahead of the fixture at the Riverside and this is how we think Leeds will line-up.
The Whites approach the contest sat second and with a three-point cushion in the division's automatic promotion spots with a game in hand.
7. Mateusz Klich
All set for an amazing 83rd consecutive Leeds United league start under Marcelo Bielsa, never missing a game. Incredible, and likely to run another 12km as he usually does from centre midfield. Picture by Bruce Rollinson.
8. Pablo Hernandez
Saturday's match-winner and happiest in the no 10 role. The Spanish magician will be looking to cause havoc to Middlesbrough's defence. Picture by Simon Hulme.
9. Helder Costa
Could do with finding an end product by way of assists or goals but still causing all sorts of bother down the right side and likely to cause Boro quite a few headaches. Picture by Simon Hulme.
10. Jack Harrison
Matters are unlikely to be any easier on the opposite flank for Boro with Harrison's pace, skill and control very impressive of late. Again, just needs the end product at present. Picture by Simon Hulme.
11. Patrick Bamford
Bielsa seems likely to keep the faith with Bamford in the lone striker role.
Always works hard but the forward has netted in just one of his last 11 games and now faces his former side. Picture by Bruce Rollinson.
