Turkish league runners-up Trabzonspor have ripped up Champions League football's formbook in style with a 1-0 win at 2010 winners Inter Milan.
Trabzonspor failed to initially qualify for Europe's elite tournament and are only in the competition after Fenerbahce were withdrawn because of match-fixing allegations, but they looked comfortable in the win at Rome's San Siro stadium.
Ondrej Celustka struck 14 minutes from time to leave Inter reeling and pile the pressure on new coach Gian Piero Gasperini after only three games in the job.
Celustka expertly hooked the ball in on the slide after Inter substitute Diego Milito spurned two gilt-edged chances.
Gasperini has now lost his first three matches in charge, including the Italian Super Cup defeat by AC Milan.
