Leeds sent out what was essentially their under-23s side as under-23s boss Mark Jackson took charge whilst Whites head coach Marcelo Bielsa also looked on from the dugout.
United left with a 3-2 victory thanks to a Crysencio Summerville penalty, a Sam Greenwood free-kick and a late strike from Charlie Allen which proved the winner.
First team midfielder Adam Forshaw also made his return from his injury nightmare as a second-half substitute as part of a contest which saw United's away fans return to a game for the first time since February 2020.
Fresh from his trip to Nethermoor, the YEP's Lee Sobot hands out the player ratings.
7. Stuart McKinstry
6 - Linked up well with Summerville on the right hand side and in the middle as the duo often swapped positions and covered for each other. One of the quieter displays but steady and got better as the game went on. Picture by Bruce Rollinson.
8. Crysencio Summerville
9 - A nightmare, for Guiseley that is; quick, skillful, adventurous and very hard to deal with when dribbling in full flow, both centrally and from the right. Won a penalty, scored it and then set up the winner. A very exciting young player. Picture by Bruce Rollinson.
9. Amari Miller
7 - A first Whites outing for the summer recruit from Birmingham City and Miller made an explosive start down the left with his pace ad skill. Not too dissimilar to Summerville in terms of style and a very promising recruit. Picture by Bruce Rollinson.
10. Sam Greenwood
7 - One of the stars of the 23s who caused loads of bother with his direct running - and his free-kicks. Possibly most recognised as a 9 but played as a 10 behind Joe Gelhardt in the front line. Looks a very classy player. Picture by Bruce Rollinson.
11. Joe Gelhardt
8 - What a talent, either as a no 9 or a 10. Played as the striker, as Marcelo Bielsa appears to see him best. Caused chaos in the first half but hobbled off injured after the break and hopefully nothing too bad. Picture by Bruce Rollinson.
12. Max Dean
6 - Replaced the injured Gelhardt in the second half. Nothing wrong with his display though chances were at a premium after the break compared to the opening 45 minutes. Picture by Bruce Rollinson.
