Aston Villa and Celtic have organised two pre-season matches in aid of Stiliyan Petrov.
The Bulgarian was diagnosed with acute leukaemia last month, leading his two British clubs to arrange the testimonial games in his honour.
It is believed that the money raised from the fixtures will be donated to leukaemia research.
The matches will be played at Villa Park and Celtic Park respectively and will also feature games between former players of both clubs.
