The Leeds United boss had one criticism for his side in the 2-1 win over Atalanta.
The Whites hosted the Serie A outfit at Elland Road in what was certainly their biggest test of pre season, but one that Monk's troops passed with flying colours.
Chris Wood's penalty on 25 minutes was cancelled out by Marco D'Alessandro six minutes later, but Kemar Roofe, who signed from Oxford United earlier this month, snatched a winner shortly after the hour mark as Leeds looked in good shape ahead of their Championship opener at QPR on Sunday.
Despite beating such a stellar opponent, the former Swansea City boss saw a few negatives and believes his side played with the handbrake on at times yesterday.
Twelve of United's 18 shots were on target, but Monk feels that Leeds could have been a tad more adventurous at times.
"I think we could've been a little bit better with the ball today if I'm honest. I don't think we were at our best with the ball," he told LUTV.
"And we could've been braver with the ball. We had a lot of young players out there, and I don't like to single anybody out. I'm not disappointed. I just think we could be a little bit braver with the ball."
Monk will be delighted with his first summer at Leeds overall, producing some excellent wins and signing some excellent players to boot.
But the 38-year-old will know that it will all count for nothing if the Whites do not enjoy a fast and furious start to the Championship campaign.
