Barcelona coach Xavi has rejected claims of favouritism from referees.
Barca are being investigated for paying former ref Enriquez Negreira's company for advice on match officials.
Reacting to the news, former Bayern Munich chief Karl-Heinz Rummenigge told Il Corriere dello Sport that every time he played in Spain he felt 'a strange sensation'.
Xavi responded, saying: "I respect all opinions, even of Rummenigge.
"But I never had the feeling of having received help to win titles, neither in Europe nor in Spain. That's for sure."
