Discussing her move, defender Dahlkemper says she was excited to hear her teammates' stories of City life, which helped to aided her decision her to join them in Manchester.
"It definitely helps, being able to talk with them about their experience," she told ManCity.com.
"They have said nothing but good things about the Club and the league in general, and they are able to play in the Champions League
"It's helped a lot, hearing from them and hearing their personal experiences like the quality of the facilities, staff, team and players.

"It's exciting for me. They definitely helped in my decision and I'm really excited to get over there and help the team in any way I can."
