Bayern Munich boss Pep Guardiola was charged by Uefa yesterday for wearing a T-shirt promoting a campaign for justice for a killed Argentinian journalist.

Guardiola wore the T-shirt stating “Justica para Topo” at a press conference before the second leg of the Champions League match against Porto.

It relates to a campaign, backed also by Lionel Messi, calling for an investigation into the death of Topo Lopez in a car accident at the World Cup.

His car was reportedly smashed into by a vehicle driven by two suspected criminals, who were being pursued by the police.

Uefa’s regulations prohibit the use of “sporting events for manifestations of a non-sporting nature” and the governing body has charged Guardiola with an “incident of a non-sporting nature.”
