At Warriors, Simutowe came into his own, cementing a regular place despite still being a teenager. He won the Castle Cup with Warriors that same year with a 1–0 victory over his former club. The following season, Warriors won the league title for the first time in their history. Simutowe, who was constantly in trouble with referees played primarily as a midfielder but he could play all forward positions. Although Warriors lost their crown to Mufulira Wanderers the following year, Simutowe had an outstanding season, finishing third on the scoring charts with 53 goals, 1 behind club-mate Kaposa and 11 behind top scorer Robertson Zulu of Wanderers. He was rewarded with the footballer of the year award and became the youngest man to lift the trophy, two months past his 20th birthday. This record would stand for 17 years until Johnson Bwalya won the award in 1986 aged 19. Simutowe also won the Sportsman of the Year award, the second footballer to do so after Samuel 'Zoom' Ndhlovu. The announcement that he had won stunned the young midfielder who disclosed that he never imagined he would win the award, and that he had learned from his mistakes in the past so he had stopped making trouble on the advice of soccer fans and officials who advised him against wrecking a promising career. The following season, Warriors regained the league title and added the Challenge Cup to their trophy cabinet. Simutowe ended the season with 55 goals and was runner-up to Kaposa who scored 58. Warriors would go on to scoop two more league titles on the trot, including the fantastic 1972 season when they swept all the silverware on offer. Simutowe played a key role in luring Godfrey Chitalu to Warriors in 1971 and in January 1973 he experienced barbarianism in football when Warriors travelled to Madagascar for an African Club Champions Cup second leg tie against Fortier Majunga at the National Stadium in Antananrivo. Warriors were leading 4–1 from the first leg in that was played in Lusaka and had just scored the fourth goal for an 8–1 aggregate lead when the hostile crowd turned on them and showered them with all sorts of missiles and Simutowe got hit on the head in a hail of stones. He still bears the scars of that attack to this day, hence the ever-present hat that he spots. Later that year, Warriors surrendered their league title to Zambia Army (now Green Buffaloes) and at the beginning of the 1975 season, Simutowe walked out on Warriors, got a job in Luanshya and announced that he would be rejoining his former club Roan United.
