The only times I can recall Lucy losing was against Flare, who cheated in her fight. She was also captured by Juvia once, but that was when she didn't have her keys so it can hardly count as a battle. While Erza lost against Jose, Jellal and Cobra in fair battles. So go rewatch the series like I told you to before insisting that Erza never loses.
