Automatic qualification for the 1970 World Cup was secured as world champions so Ramsey led England on a pre-tournament tour of South America. The effects of altitude on the team led Ramsey to appoint the first full-time team doctor, Neil Phillips, who helped prepare the squad for the forthcoming tournament in Mexico. England were defeated in the quarter-final by West Germany; with a 2–0 lead with 25 minutes of the match remaining, Ramsey substituted Bobby Charlton and goalscorer Martin Peters, but West Germany went on to win 3–2 after extra time. Ramsey was heavily criticised in the British press for the substitutions. Losing out to West Germany again, this time in a two-legged quarter-final for Euro 1972, Ramsey prepared England for qualification for the 1974 World Cup. Needing a win against Poland, Ramsey's tactical use of substitutions was again called into question as the match ended in a 1–1 draw. England had failed to qualify for the World Cup, and Ramsey was dismissed the following May.
