Sperrle and Richthofen made an effective team in Spain. Sperrle was experienced, intelligent with a good reputation. Richthofen was considered a good combat leader. They combined to advise and oppose Franco to prevent the misuse of their air power. Both men were blunt with the Spanish leader and although the Germans and Spanish did not like each other, they developed a healthy respect which translated into an effective working relationship. Richthofen and Sperrle agreed German support should be limited, for Franco's rule would not be perceived as legitimate if he received lavish foreign aid. Their view was reported to Berlin.
