"I think it's a good move for Asisat Oshoala," Dennerby told Goal.
"It's really a good team with lot of skilful players and a nice environment for her to improve ahead of the Women's World Cup.
"I definitely believe she will excel at Barcelona. Although they are a talented team, her speed will always be useful for them.
"I will tell her to keep on using her best skills to better the fortunes of the team and her own game."
Having been handed jersey no. 20, Oshoala is in line to play her first game at Ciutat Esportiva Joan Gamper on Sunday when Barcelona face Albacete in a Spanish topflight game.
