A Portugal fan who ran on the field to get a selfie with Cristiano Ronaldo will cost his national football federation a fine, UEFA has announced.

UEFA says it has opened a disciplinary case against the Portuguese federation for a "field invasion."

UEFA holds national teams responsible for the behaviour of their fans inside a stadium.

The man ran across half the field from behind one goal at Parc des Princes after Portugal drew 0-0 with Austria on Saturday.

He caught up with Ronaldo near the halfway line, and Ronaldo gestured to a security official to stay back until the fan got the picture before the fan was led away.

Meanwhile, UEFA has charged the Hungarian football federation for fan disorder inside the stadium during their match against Iceland in Marseille and charges over the setting off of fireworks and throwing of objects have also been levelled at the Royal Belgian Football Association after their 3-0 victory over Republic of Ireland.
