Speaking after his side's 3-2 defeat at the hands of Swedish club Mjallby, he admitted the three-match tour had been a learning curve and a valuable experience.
The Wanderers boss told the club's official website: "Overall, it has been a very productive training camp. We've come up against opposition who are further down the line than us in terms of preparation."
When asked about the Mjallby loss, Freedman added: "We started really well and in the opening 20 minutes we found ourselves two goals up.
"We were looking really good going forward, then they got back into the game.
"That may have been because we're now at the end of our training camp and our players were a little fatigued.
"Our recovery runs in the latter periods of the first half were a little slow and that resulted in Mjallby scoring three quick goals.
"We were a lot better (in the second period) and created four or five really good chances and should have probably gone on to win the game."
The Trotters' next pre-season fixture is on Friday evening, when they visit Conference side Macclesfield Town.
