Liverpool defender Virgil van Dijk appeared to stamp on the penalty spot just before Jarrod Bowen's effort was saved by Alisson in the Reds' 1-0 win over West Ham on Wednesday night.
Jurgen Klopp's men secured their second successive victory in the Premier League and look be gaining their confidence back following a difficult season so far - but it was not straightforward against the Hammers as Darwin Nunez's strike proved to be the only goal of the game.
And West Ham could have snatched a result from the game had Bowen not missed his effort, though some eagle-eyed fans spotted that just before he fluffed his effort, Van Dijk had appeared to put his studs into the penalty spot.
