As of now, there is no public record of Brentford manager Thomas Frank making a prediction about the outcome of Arsenal's Champions League clash with Real Madrid. Frank has previously praised Arsenal's prowess, particularly highlighting them as "the best set-piece team not only in the Premier League but in the world right now".

In the lead-up to the second leg of the Champions League quarter-final, Arsenal manager Mikel Arteta emphasized the need for his team to remain brave and determined to prevent a Real Madrid comeback, despite holding a 3-0 lead from the first leg.

While Frank has acknowledged Arsenal's strengths in past comments, he has not publicly offered a prediction regarding their Champions League performance against Real Madrid.
