This is where the Europa League gets real for Spurs.
Mauricio Pochettino's side drew their opening Group C game 0-0 at Partizan Belgrade and, depending on which way you look at the result, it could have been seen as a point gained or an opportunity missed.
But tomorrow night's clash with Besiktas is a must-win game if Tottenham are serious about their European aspirations this season. How you fare against the stronger sides early on is often an indication of your tournament credentials.
More importantly, meanwhile, Pochettino's men are at home - and therefore have to get a result.
The north London side were in training today to finalise preparations in order to achieve that against the Turkish side - who boast former Chelsea striker Demba Ba in their ranks. Besiktas were only just knocked out in the Champions League play-offs by Arsenal, whom Spurs drew with at the weekend.
Pochettino, it seems, plans to play a strong Tottenham side against Ba and co, with the likes of Benjamin Stambouli, Frederico Fazio and more all pictured during today's practice session. Roberto Soldado, who often looks to the Europa League for inspiration, also featured prominently.
