Switzerland completed a dramatic turnaround to defeat Serbia on Friday but the duo who came to their country's rescue have found themselves in hot water.

Goalscorers Granit Xhaka and Xherdan Shaqiri are facing two-match bans for their celebrations after FIFA opened an investigation into a potential breach of their political and offensive messages regulation.

Both players, ethnic Albanians from Kosovo, made 'double eagle' gestures after scoring which symbolise the Albanian flag.

A Serbian crackdown on the Albanian population only ended with Nato military intervention in 1999.

Elsewhere, an audio clip reportedly of Atletico Madrid coach Diego Simeone describing Argentina as "anarchy" went viral following the South Americans 3-0 loss to Croatia.

Since then, talk of a dressing room revolt has surfaced, with the squad reportedly keen to oust Jorge Sampaoli from his role as manager ahead of their final group game against Nigeria.

According to reports, Argentina's players voiced their displeasure regarding Sampaoli to general manager Ricardo Burruchaga and will now "pick the team" for their crunch fixture against the Super Eagles.

Midfielder Javier Mascherano has denied talk of a rift, however.
