Arsenal boss Unai Emery has named unknown goalkeeper Deyan Iliev in his 21-man squad for his side's Europa League semi-final second leg against Valencia.
The Gunners, who travel to the Mestalla holding a 3-1 lead, announced their travelling party on Wednesday afternoon.
Iliev was the surprise name included in Emery's squad as he as yet to make a senior appearance for Arsenal.
The 24-year-old is a Macedonia Under-21s international and has featured eight times for the North London outfit's reserves in the Premier League 2.
However, Bernd Leno and Europa League regular Petr Cech are also part of the squad and are likely to make the cut for the final 18 on Thursday.
Arsenal won the first leg thanks to two goals from Alexandre Lacazette and one from Pierre-Emerick Aubameyang late on.
