Juventus fell to a 1-0 defeat to Sevilla on Tuesday night and in the process lost top spot in Group D as Manchester City came from behind to beat Borussia Monchengladbach 4-2.
The Bianconeri needed just a draw in Seville to hold on to first place and in turn avoid many of the most dangerous sides remaining in the competition, but their former striker came back to haunt them as Llorente headed home the winner in the second half.
Having struggled to get the best out of himself in Turin, the Spanish striker returned to his homeland in the summer and ultimately made the Italian giants regret the decision to let him go.
It may prove even more costly depending on the draw for the round of 16, as Juve will certainly be left kicking themselves after they were unable to hold on in the final game to secure top spot.
City had looked as though they were set to throw away the chance to take advantage, but three goals in the last 10 minutes against Monchengladbach swung the game firmly back in their favour and ensured that Manuel Pellegrini’s side topped the standings.
While Juve finished with 11 points from their six games, including two wins over City, the Premier League side ended with 12 as the results on Tuesday night also enabled Sevilla to qualify for the Europa League while Monchengladbach drop out of Europe entirely.
