Clubs’ participation in the tournament has been controversial, with some questioning the timing and the risk of injury with Euro 2025 starting on 2 July.
Rosengard face BK Hacken in the Swedish league on Saturday (14:00 BST) but travelled to Estoril to take part.
“We had some reactions in Sweden, that we came here, because we have a game,” said Rosengard midfielder Emelia Larsson.
“For us, it’s like taking a break from all of it. You miss a training week, but if you put that aside, I think it’s just really fun to be here.
“It’s a good opportunity to show ourselves and show Swedish football.”
Manager Joel Kjetselberg said it was good practise to prepare for Champions League football, for which they would travel midweek, in between weekend matches.
City held around five training sessions to prepare for the World Sevens, while United had one.
“We would only be doing this in training all week anyway,” said United’s Clinton.
“If we were going into the next England camp, we would all have just been doing small-sided games anyway.
“This is probably a better outcome and gives us more fitness.”
