Is Fernandes' own goal the worst of all time?
Porto defender Martim Fernandes made the headlines for all the wrong reasons during Thursday's Europa League quarter-final draw with Nottingham Forest by scoring a bizarre own goal. Fernandes, 20, beat his own goalkeeper Diogo Costa from 45 yards with a misplaced backpass to level up the first leg, which ended 1-1. To make matters worse, the Portuguese then suffered an injury minutes later and had to be substituted.
But is Fernandes' own goal the worst of all time? BBC Sport looks at some of football's most infamous OGs. Lee Dixon chipped David Seaman from 25 yards out in a First Division match against Coventry Former Arsenal duo Lee Dixon and David Seaman were part of a formidable backline for the Gunners during the 1990s and early 2000s - and both also featured for England.
Indeed, such was the Gunners' strength at the back that '1-0 to the Arsenal' became a familiar chant from the terraces. But in 1991, Dixon and his goalkeeper were certainly not on the same page when he attempted a long-range back pass to Seaman in a match against Coventry at Highbury. And the right back gave his goalkeeper no chance when the ball sailed over Seaman's head and into the net.
Jamie Pollock was left red-faced by his misplaced header against Queens Park Rangers On the penultimate weekend of the 1997-98 First Division season, Manchester City hosted Queens Park Rangers knowing they needed a result to give themselves the chance of avoiding relegation down to England's third tier. But they didn't count on Jamie Pollock doing his best Paul-Gascoigne-versus-Scotland-at-Euro-96 impression - only at the wrong end of the pitch. Pollock somehow managed to flick a QPR cross high into the air and, in one graceful movement, head the ball over goalkeeper Martyn Margetson and into the net to put City's opponents 2-1 up.
City would equalise to earn a 2-2 draw. But despite a 5-2 win at Stoke on the final day, they were relegated to what is now League One by a single point. Franck Queudrue went on to become a League Cup winner with Middlesbrough Franck Queudrue spent nine years in English football, featuring for Middlesbrough, Fulham, Birmingham and Colchester, but it was months prior to leaving boyhood club Lens in 2001 that he produced one of the most iconic own goals of all time.
