Just a few days prior to Manchester United’s giant clash with defending Premier League champions Chelsea, Jose Mourinho is being forced to adapt his preparation tactics.

The Portuguese boss has reportedly been called to Spain to appear in front of a judge in Pozuelo de Alarcon as charges of tax fraud continue to swirl around Mourinho from his days as manager at Real Madrid.

The charges state that Mourinho defrauded the Spanish government of over $3.8 million while managing Los Blancos.
