Union Berlin secured a 1-0 victory at Borussia Monchengladbach on Sunday courtesy of a sumptuous Sheraldo Becker volley to remain in third place and stay on course for a Champions League-qualifying spot with five matches remaining.

The visitors, having their best ever season, had the upper hand for an hour but could not break the deadlock until Jerome Roussillon floated a perfectly-timed left-foot cross into the path of charging Becker and the Suriname winger volleyed home.
