#5 Mario Mandzukic (Atletico Madrid vs Juventus)
The Atletico Madrid vs Juventus fixture will have one player on each side facing his old employers. Mario Mandzukic will be visiting his old club mates as the two sides lock antlers in the round of 16.
The Croatian striker may have played only one season with Atleti, but the fans still fondly remember him for his emphatic goal-scoring skills in a 4-0 win against Real Madrid. During that season, he netted 20 goals in 43 games for the Rojiblancos.
Four years down the line, Atletico will be facing a fan-favourite Juve striker known for his impeccable goalscoring skills, something they don't need an introduction to. Given that Juventus are the favourites to go through to the next round, it remains to be seen if Mario Mandzukic proves to be the man to put his former club to the sword.
