Aston Villa captain John McGinn is in line for an Easter Road return after his side were paired with Hibernian or Luzern in the Europa Conference League play-offs.
The Scotland midfielder will be back in Leith on August 24 if Hibs can get past the Swiss side in the third qualifying round.
McGinn spent three years with Hibs and helped them win the Scottish Cup in 2016 for the first time in 114 years, before moving to Villa in 2018.
The Champions League draw earlier saw Rangers set up for a potential reunion of their own after they were paired against PSV Eindhoven or Sturm Graz if they progress.
The Ibrox side were seeded in the draw but must first get past Swiss side Servette, who travel to Glasgow on Wednesday in the first leg of the third qualifying round.
The Gers beat PSV 3-2 on aggregate at the same stage last year to reach the group stage, with Antonio Colak grabbing the winner when he netted the only goal of the second leg in the Netherlands.

Sturm Graz have included former Motherwell wing-back Max Johnston in their European squad, although he has only featured for the second team since his recent move.
Rangers would be at home in the first leg of the play-offs, which take place in the final two weeks of August. Defeat against Servette would see them go straight into the Europa League group stage.
Aberdeen could also face a rematch with recent opponents after being paired with either BK Hacken or Lithuanians Zalgiris Vilnius in the Europa League play-offs. The Dons beat the Swedes 5-1 at Pittodrie two years ago.
Barry Robson’s team are assured of group-stage football as they will drop into the Europa Conference League if they lose.
Also in the Conference League, Hearts will take on Croatians Hajduk Split or Greek side PAOK if they can get past Rosenborg. Derry City will face Czech side Viktoria Plzen or Gzira United of Malta if they can see off Tobol Kostanay of Kazakhstan.
Play-off ties take place over the last two weeks in August.
