Portugal 13-2 after late goal knocks out Croatia
Portugal are 13-2 with bet365 to win Euro 2016 after beating Croatia 1-0 after extra-time following a dour last-16 game.
Portugal made it four successive draws in the tournament as neither side managed a shot on target in 90 minutes.
Penalties were looming when Ricardo Quaresma broke the deadlock with a 116th minute header as he followed up a Cristiano Ronaldo shot.
Only three goals were scored in normal time of the opening three last 16 games, with Poland beating Switzerland on penalties after a 1-1 draw in the first match and Wales ending Northern Ireland's hopes with a 1-0 win through a Gareth McAuley own goal.
Wales, who face Hungary or Belgium in the quarter-finals on Friday in Lille, are 22-1 from 28-1 to win the tournament.
Poland, who will meet Portugal in Marseille in the first last-eight clash, were cut to 18-1 from 28-1 after their shootout success.
France are still just shading overall favouritism at 9-2 but BoyleSports and Hills make them joint-favourites with Germany.
England, who are 11-20 to win their last-16 game against Iceland on Monday, are 10-1 shots. They will meet the winners of Sunday's game between France and Ireland. Martin O'Neill's men are 19-2 to upset the hosts.
