The Liberty Stadium outfit were beaten 2-0 by Minnesota United but the club's 35-year-old manager is unconcerned by the result and happy with how training is progressing
The 35-year-old manager admits the Swans were second best against the American minnows, but is convinced the gruelling two-week training camp in the United States will toughen his players up for the rigours of another Premier League season.
The Welsh outfit have been put through their paces this summer by their new boss and Monk, who is overseeing is first pre-season as a manager, is confident their hard work will be rewarded when the new season starts.
"Without taking anything away from Minnesota because they deserved the victory, our energy levels just weren't there," Monk told the club's official website.
"But while we always want to win because winning breeds confidence, we can't let the result detract from a very successful two weeks for the boys.
"They have worked extremely hard and the level we are at is very good because of that training.
"But perhaps the 90 minutes [against Minnesota] was a bit too much because of the work we've been doing.
"I've been very hard on them and that showed.
"The key thing is that the players will feel the benefits when they return to training next week.
"I've really enjoyed the training and putting them through their paces.
"I've been very hard on them and enjoyed seeing them sweat. The boys know that if they hurt now and they get through the tough periods then they'll be fitter for it and in a better place to go into the season."
