Juventus forced extra time against Porto in Tuesday's second leg of their Champions League last-16 tie after overturning a 2-1 deficit from last month's first leg in Portugal. Sergio Oliveira's first-half penalty at the Allianz Stadium increased Porto's advantage but Juventus levelled the tie through two goals from Federico Chiesa, which came either side of Porto striker Mehdi Taremi's red card. mw/jc
