Who is Joao Pinheiro? The referee for Argentina vs Switzerland?

The last quarter final game takes place on Saturday between the defending World Cup winners and European underdogs

We are at the business end of the World Cup now and this is the last of the quarter finals between defending champions Argentina and European underdogs Switzerland

The winner of this quarter final will go on to face England or Norway in the semi-finals in Atlanta on July 15.

There are only two games on Saturday and this is the second of the two.

The clash is set to be played at Kasas City Stadium, with kick-off set for 2am UK time.

The referee for the occasion is Portugal's Joao Pinheiro.

This will be the 38 year old's third game of this World Cup, which is Pinheiro's first-ever major international tournament outing.

His last game was Canada's 1-0 win over South Africa and before that he took charge of Switzerland's somewhat bizarre victory over Bosnia and Herzegovina, with the Swiss running out 4-1 winners despite not opening the scoring until the 74th minute.

That late flurry of goals came after Pinheiro showed Bosnian Tarik Muharemovic a straight red card for a DOGSO offence with ten minutes to go.

Pinheiro will be joined by his fellow countrymen Bruno Jesus and Luciano Maia as assistant referees.

In addition, Canadian official Drew Fischer will serve as the fourth official.
