Petrasso was handed just his third start of the season for QPR at Turf Moor, and he put in an impressive performance against the Clarets.
Petrasso was a constant threat in attacking positions for QPR, and he played without fear throughout the contest.
The 20-year-old looked QPR’s brightest outlet for much of the contest, and he insists that Hasselbaink’s words were a help to him on the field.
“My game revolves around dribbling and pace, so I try to take my opportunities when I can in the wide areas and take people on,” Petrasso said. “I will try and stick to that and hopefully I will succeed.
“The gaffer told me before the game to be confident, do what I do in training and try to express myself on the field. Hopefully I did that.”
Despite Petrasso’s encouraging showing, QPR were unable to upset the odds to claim a result against Burnley.
Sean Dyche’s side were forced to fight for the three points, but they did enough to claim the victory thanks to Sam Vokes’ header.
Burnley’s win confirmed that they will be back in the Premier League next season, and they can win the league if they are able to beat Charlton Athletic on the final day of the campaign.
QPR, meanwhile, are destined to finish in mid-table this season, with their final game coming against Bristol City.
