The Spanish full-back looks ludicrous in his silly outfit, after losing a bet with Jose Enrique.
Of course he hasn't. Manquillo is as svelte as ever but the extra padding in this daft Halloween costume he has on certainly does no favours to the figure.
This is once again a product of a Jose Enrique video on Instagram - where the two Spanish Liverpool team-mates have again been larking about off the pitch.
Enrique has taken Manquillo under his wing since he arrived at the club from Atletico Madrid on loan this summer - with a number of amusing posts on the player.
It seems that once again Manquillo lost a bet with the more senior Spanish full-back at Liverpool. The result is him wearing what is either a devilish clown suit or a goth John McCririck goes to Oktoberfest look - either or.
Hilarity ensued as once again the Liverpool newbie is not afraid to make a fool of himself for the good of a bet.
