FC Porto have become the latest European heavyweights to take up residence at St. George's Park, as they prepare for the new season.
Following the training visit from FC Barcelona, the Portuguese giants checked into St. George's Park on Sunday evening after arriving in England to feature in the testimonial for Three Lions and Everton midfielder Leon Osman at Goodison Park, which ended 1-1 earlier that day.
Colombia World Cup star Jackson Martinez scored the goal for the Dragons in that game after reporting back to Porto for pre-season last week.
Martinez and his team-mates will now be spending the rest of the week in Burton under new boss and former Spain U19s and U21s coach Julen Lopetegui, as they continue to prepare for their Primeira Liga and Champions League campaign, following a third-placed finish last season.
Porto are one of five clubs, alongside England's Arsenal, to enter the Champions League at the play-off stage in late August.
They will next be in action on Saturday when they take on West Bromwich Albion at the Hawthorns, before heading back to Portugal to continue their build-up to the new season.
