Barcelona players were kept awake the night before their second-leg fixture against Liverpool at Anfield on Tuesday night.
Ernesto Valverde's side hold a 3-0 lead from the first-leg at Camp Nou last week as they look to be in pole position for a place in the Champions League final.
The Barcelona squad, many of whom were rested at the weekend, made their way to Liverpool from Catalonia on Monday afternoon ahead of the decisive semi-final tie.
Valverde led his team out at Anfield for a training session soon after arrival before the squad returned to their team hotel, The Hilton in Liverpool city centre.
If the players were hoping for a peaceful night's sleep in preparation of the game, they were sorely mistaken.
In videos surfacing social media, a Liverpool fan sets off a barrage of fireworks outside the hotel in what is assumed to be in the early hours of Tuesday morning.

Never heard fireworks as loud as the ones that have just been set off by the Hilton in Liverpool city centre.
Not a chance the whole Barcelona squad hasn’t just been woken up.

The Reds are extremely unlikely to overturn the 3-0 deficit from the first-leg, however some supporters are evidently trying to do their part to give Jurgen Klopp's side an unexpected advantage.
