Former Barcelona trainee involved with the first team ahead of Bayern game.
Could Arsene Wenger name a surprise name or two amid the team selection against Bayern once again?
In the first leg it was Yaya Sanogo selected to start, illustrating the Frenchman is not likely to shy away from making big calls.
Youngsters Jon Toral, Isaac Hayden, Ryo Miyaichi and Kristoffer Olsson all featured in first team training at London Colney on Monday.
It is unclear as to how many of the quartet - including Toral - have travelled to Germany, due to Arsenal not releasing an official travelling squad list.
If Toral has travelled, the best he is likely to hope for is a spot on the bench against Bayern, with Arsenal having plenty of options in attacking positions.
Should Wenger make such a decision to throw in one or two youngsters even as substitutes, it could work either way. It could be fantastic experience for them and be a chance for them to make a name for themselves, or a haunting one if this spectacular Munich side is as ruthless as it has been in previous weeks.
Toral, 19, returned to action late last year after injury stunted his progress since signing from Barcelona, and recently netted his fifth of the season in a win against Shakhtar in the UEFA Youth League.
If it transpires he has not in fact travelled to Munich, the elevation to the first team training set up is certainly a sign of his progress and the faith Wenger has in him, especially in the build-up to such a huge game. Mixing with the club's top stars can only help his path to fulfil his potential and achieve stardom at the club.
