Watch: Sturridge sings in empty dressing room following postgame drug test

Daniel Sturridge was forced to celebrate alone on Thursday.

After scoring in Liverpool's 3-1 victory on aggregate over Villarreal to secure the Reds' first return to a European final since 2007, Sturridge was forced to undergo a drug test. By the time it was done, the Merseyside club's dressing room was empty, resulting in the English forward singing about his loneliness.

Liverpool will take on Sevilla, the two-time reigning champion, in the Europa League final at St. Jakob-Park on May 18.
