West Ham midfielder Tomas Soucek joined in the celebrations after Slavia Prague's shock win at Leicester City in the Europa League on Thursday night.
After a goalless draw in the first leg, the visitors faced a daunting task to reach the last 16 against Brendan Rodgers' high-flying side.
Soucek had shown his support for his old club with an Instagram post showing him watching the game and wearing a Slavia Prague top.
Lukas Provod and Abdallah Sima struck in the second half to settle the last-32 tie 2-0 on the night and on aggregate.
