- The trio have been described as doubts prior to the match.
- Luiz's participation looked particularly unlikely as the centre-back seems to have picked up a hamstring strain.
- However, Chris Wheatley spotted him - as well as Laca and KT - in full training.
Tierney has been absent for almost a month after picking up a knee injury vs Liverpool. Many feared his season was over as even the possibility of surgery was raised - but mercifully he's made a swift recovery.
Lacazette limped off with a hamstring injury several weeks later but also appears back in the fold; meanwhile, Luiz pulled up just this weekend with many fans concerned his muscle issue was a season-ender.
How much Arteta would be willing to risk any of them remains to be seen. Should we go through tonight, having the trio available for the final is much more important.
