Arsenal coach Unai Emery has urged his players to rise to the challenge and seal their place in the Europa League final when they face his former side Valencia in the second leg of their last four tie.
Emery's side hold a 3-1 lead ahead of his return to Mestalla for the second leg on Thursday, with the English club likely needing to win the tournament to qualify for next season's Champions League.
The Spaniard had a four-year spell in charge of Valencia and also worked at Sevilla and Paris Saint-Germain before taking over at Emirates Stadium last year.
