LONDON – Arsenal defender William Saliba called Porto “smart and experienced”, but he remained confident they can overturn a 1-0 deficit in the second leg of their Champions League last-16 tie at the Emirates Stadium on March 12.

Arsenal failed to get a shot on target despite having the majority of possession in the first leg, with Galeno’s 94th-minute wonder goal condemning them to defeat at the Estadio do Dragao.
