The Championship side came out on top against Serie A side Atalanta at Elland Road.
Leeds manager Garry Monk
Ronaldo Vieira has told Leeds United's official website that while he thought Garry Monk's men played well in their final pre-season friendly with Atalanta, he felt that there was one aspect of their game that the squad could look to improve.
The Whites geared up for their first game of the new Championship season this weekend by claiming a narrow 2-1 victory over the Serie A side at Elland Road.
And while Vieira - who put in a man of the match display for the Peacocks - reflected positively on the performance as a whole, he did suggest that improvements still needed to be made.
"I thought we did well on Saturday," he told the club's official website.
"We practiced throughout the week for the game and we put in everything we practiced - maybe we could just keep the ball a bit better but that will come.
"It's always important to get a win because that motivates the team and everyone around it – we're going into the first league game very motivated."
To pick up such a result against a side from a division as prestigious as the Italian top flight will have undoubtedly boosted the team's confidence heading into what promises to be a tough game against Queens Park Rangers on Sunday.
But Monk will be keen to ensure that the players do not get carried away with the win, especially as they lost to Peterborough in their previous game, as Jimmy Floyd Hasselbaink's men will surely have enough quality to punish them if they go into the contest with any complacency.
However, with Vieira admitting that there are areas for improvement, it is clear that United will go into the game under no illusions that they have plenty of work to do.
But if they can couple that with the confidence of knowing what they can be capable of, then they arguably have an excellent chance of getting their campaign off to a good start.
