Virgil van Dijk was left hobbling from the pitch in the Merseyside derby after a horror challenge from Everton goalkeeper Jordan Pickford.
Pickford came surging out of his goal in the early stages of the match and clattered into Liverpool defender Van Dijk in a scissors motion, crunching the outstretched knee of the Dutchman.
Van Dijk immediately collapsed in a heap and needed extensive treatment in the area, before having no option but to leave the field.
Huge questions were immediately asked of Pickford, who was lucky to escape a red card and penalty kick due to Van Dijk being in a marginally offside position.
