The 21-year-old livewire has returned to his parent club Benfica following a season long loan with Forest.
Prior to their crucial final match of the season, Nottingham Forest boss Mark Warburton allowed Pajtim Kasami, Nicolao Dumitru, Joao Teixeira and Hildeberto Pereira to return to their parent clubs, with the players experiencing varying degrees of success.
Dumitru has gone down as one of the worst players to play for the club, Kasami frustrated fans by showing glimpses of his ability - but without any consistency - while Teixeira didn't manage a single minute for the first team.
That leaves Pereira left, who both endeared and aggravated Forest fans in his time at The City Ground - but what no-one can say, is that Pereira was a boring player.
With explosive speed and brilliant trickery, Pereira was outstanding flying forwards for Forest - as demonstrated by his amazing goal in a 3-1 win over Birmingham City or his dazzling assist for Henri Lansbury's equalising goal against Aston Villa in a 2-2 draw, which saw Pereira leave three defenders in his wake before squaring it.

However, he was also incredibly emotionally invested - perhaps too much at times, as demonstrated by his staggering disciplinary record, which saw Pereira pick up four yellow cards and three reds while he was on Trentside.
In total, the 21-year-old winger/full-back got two goals and two assists in 25 appearances in all competitions, displaying immense potential and ability in the process, however Forest also had to deal with the lack of experience he was sent to the club initially to learn.
Forest fans may never see a player as exciting - for better or worse - as Pereira again on a temporary basis, though it's unlikely that the Portugal U21 man's antics will be forgotten about in a hurry on Trentside, and few Forest fans would wish Pereira misfortune following his whirlwind of a loan spell.
