Five-time Ballon d'Or winner Cristiano Ronaldo was visibly furious after the final whistle as Portugal were held to a draw by Scotland on Tuesday night.

Portugal all but sealed a berth in the Nations League quarter-finals with a 0-0 draw away to Scotland on Tuesday, the first points Roberto Martinez's side have dropped in their four games.

The Portuguese maintained top spot in Group A1 with 10 points, three ahead of Croatia, who drew 3-3 with Poland in Tuesday's other game in the group, while Steve Clarke's struggling Scotland side are last on one point. Third-placed Poland have four points with the top two in the group moving on to the last eight.
