Vieira has emerged as one of the surprises of the season for Leeds United this term.
The 18-year-old went into the campaign very much on the periphery of the squad having only made his first-team debut on the final day of last season with a one-minute cameo in the draw with Preston North End.

However, under Garry Monk, Vieira has quickly become an important man for the team. He has made 13 appearances this term in all competitions, and bagged the winner in the Whites' most recent game with a long-range stunner in stoppage-time against Norwich.
And following the game, he has admitted that he would not have expected used so often at the start of the season.

"It's very good and I never thought that this season I would be involved the way I am involved with the first team," Vieira told the Yorkshire Evening Post.
"It's something different to me but I am trying to get into it and try and get used to it and it's been good so far."
Liam Bridcutt perhaps faces a battle to get back into the team
The form of Vieira and fellow academy graduate Kalvin Phillips has undoubtedly been one of the most pleasant surprises for Leeds fans this term.
Neither youngster has looked out of place in the second tier, and their form has arguably meant that United skipper Liam Bridcutt faces a battle to get back into the team once he returns from injury.
And given how imperative it seemed that the Whites brought Bridcutt back on a permanent deal in the summer, it is remarkable to now think that Monk could leave the former Sunderland man out without raising many eyebrows.
