Arsenal manager Unai Emery may have just let slip what his plans are for the Gunners' Europa League semi-final second-leg tie at home to Valencia.
The Gunners have been preparing for the upcoming clash at the Emirates by practicing at the club's training ground and it seems the Spaniard has let his tactics slip ahead of the first-leg at the Emirates.
A photographer, taking images during the session, managed to capture tactical information on the Arsenal bosses clipboard, which not only showed his side's potential line-up for the tie, but also showed what formation the Spanish side can expect to face tomorrow night.
According to the image, below, the Gunners are set to play 3-4-1-2 at the Emirates, with Mesut Ozil playing behind Pierre-Emerick Aubameyang and Alexandre Lacazette in attack.

The Gunners come into the game on the back of three straight defeats, with a 3-0 drubbing at Leicester City on Sunday afternoon the latest in their poor run of form.
And as a result, their hopes of a top finish are now hanging by a thread, with Europa League glory potentially being the only route into next season's Champions League for Emery's side.
