Luiz Felipe Scolari

Scolari left Brazil after the success and took charge of Portugal, coming up against his home nation in his second match.
It had been 41 years since Portugal had last beaten Brazil, but Scolari brought an end to that long wait with a 2-1 victory against a team that consisted of Ronaldo, Ronaldinho and Rivaldo.

Won 1-0 with Chile in 2010 World Cup qualifying
After losing 2-0 to his own country the first time Chile came up against Argentina in the 2010 World Cup qualifiers, Marcelo Bielsa got revenge with an important victory in 2008.

Won 2-0 with Australia in 2008
Australia looked doomed to another defeat at the hands of a top nation after Klaas-Jan Huntelaar gave Netherlands the lead six minutes into their friendly in Eindhoven in 2008.
But the Socceroos, coached by recently appointed Dutchman Pim Verbeek, fought back when Maarten Stekelenburg was sent off at the end of the first-half, allowing Harry Kewell to level the game with a penalty.
Australia capitalised on their numerical advantage to go ahead in the second period when Joshua Kennedy headed past substitute goalkeeper Henk Timmer.
Verbeek's Australia came up against Oranje again in 2009, drawing 0-0.
But Oranje came up against a familiar face when they were paired with a Russia side led by Dutch coach Guus Hiddink. Russia demolished Marco van Basten's team 3-1 in the quarter-finals, before being outclassed by Spain in the next round.
Reaching the World Cup quarter-finals in 2010 and the Copa America final the following year will stand out in his mind, but so too will the important 1-0 victory over Argentina in 2009.
Near the end of the qualifying campaign for the tournament in South Africa, Tata orchestrated a 1-0 win over an Albiceleste team coached by the legendary Diego Maradona and consisting of Lionel Messi, Sergio Aguero and Javier Zanetti.
