text: Pep Guardiola has denied claims of a dispute with former Bayern Munich club doctor Hans-Wilhelm Muller-Wohlfahrt, who quit the club on Thursday after 'being blamed' for the defeat by Porto. The 72-year-old, who had worked at Bayern for almost 40 years, sensationally quit the Bundesliga club, claiming 'the bond of trust is damaged', but Guardiola has played down claims of a feud. 'The reaction is on me, I was disappointed,' he told reporters in the wake of a shock Champions League quarter-final defeat by Porto. 'It was nothing to do with the doctor. Pep Guardiola has denied a rift with the former Bayern Munich doctor who quit the club this week . Hans-Wilhelm Muller-Wohlfahrt (right) quit the club, claiming the medical staff had been blamed for defeat . 'After the Champions League match of Bayern Munich against Porto the medical department was for some inexplicable reason made primarily responsible. The bond of trust is damaged.' 'I've been informed of the doctor's decision and I fully respect it. Nothing happened between us, it was his decision. Injuries are part and parcel of football, they're not the medical staff's fault.' Muller-Wohlfahrt's decision came after Bayern boss Guardiola appeared to imply that Wednesday's defeat was down to a lack of available players, commenting post-match: . 'We have players who were out a long time with injuries. Their legs don't last very long. It's a tough result to take into the second leg, but we'll give it a go.' Bayern had just 14 fit players to choose from at the Estadio do Drago, with Mehdi Benatia, Franck Ribery, Arjen Robben, Javi Martinez and David Alaba among the first-team regulars missing.

Guardiola also appeared to publicly humiliate Muller-Wohlfahrt eight days before his exit from the club, sarcastically clapping him when Benatia left the pitch injured. Continuing at his press conference on Thursday, Guardiola said: 'The responsibility for the defeat in Porto lies with me. Put together, my players have had 30 operations over the last two years, but we've still won the league and cup. 'We can't win every match 3-0 or 4-0 in this situation. It's impossible.'
