"The trial for a fourth substitute to be allowed in extra time will be extended to four Uefa tournaments this summer, the governing body has announced. Teams at the women's Euros and Under-19 Championship, as well as the men's Under-21 and Under-19 Championships, will all be allowed the extra change. Uefa will also continue to trial the 'ABBA' penalty system."
