Following a damaging home defeat to Motherwell, Danny Rohl has plenty to ponder with Rangers' Scottish Premiership title hopes hanging by a thread.
A trip to face league leaders Hearts is being billed as a must-win fixture for the Ibrox side, who sit four points off the summit with four games remaining.
But how should the German head coach approach the Tynecastle showdown?
Having seemingly settled on a 4-2-2-2 shape, Sunday's loss to Jens Berthel Askou's side has thrown Rohl's preferred system into question.
In a sensational first-half performance from the Steelmen, Rangers were toyed with and were fortunate to head into the interval just two goals down.
Motherwell were able to outnumber Rohl's midfield and cut through the heart of his team, with Emmanuel Longelo and Tawanda Maswanhise deployed as wide forwards to pin back the home side's full-backs.
Although Rangers were ultimately undone late on, a half-time switch to a 4-3-3 allowed them to be more compact in central areas, while the introduction of Mikey Moore gave them far more threat in attack.
The Tottenham youngster's minutes have been carefully managed lately following fitness issues, but fans of the Ibrox club will be desperate to see the teenager start at Tynecastle.
Rohl's 4-2-2-2 system worked well for Rangers in their 4-2 win over Hearts in February, but that was with striker Ryan Naderi fit to partner Youssef Chermiti and left-back Tuur Rommens available.
The fitness of the duo who missed Sunday's loss could determine Rohl's decision-making, with his team likely needing a victory against a side who remain unbeaten at home in the league this season to thrust themselves back into contention.
"We have to just look at the next game - Sunday has passed," Rangers podcaster Scott Cameron said on the BBC's Scottish Football Podcast.
"It was disappointing. It was another Jekyll and Hyde Rangers performance, but we go to Tynecastle on Monday and we can win at Tynecastle.
"Admittedly, Hearts have got a fantastic home record, but I think the approach has to be to go out and win the game and then take it from there.
"We've blinked first, but we have to bounce back with three points."
