The World Cup has now reached the end of its fourth week. Here we look at some of the tournament's controversies over the past seven days.

ROONEY RED MIST

Wayne Rooney's sending-off dealt England's hopes of advancing beyond Portugal in the quarter-finals a serious blow. The striker appeared to stamp on Ricardo Carvalho as they tussled for the ball and then pushed Cristiano Ronaldo away as his Manchester United team-mate came in to remonstrate with the referee. England were incensed by Ronaldo's actions, with the player later caught on camera winking at the Portugal bench.

ARGENTINA LOSE THEIR COOL

Argentina's quarter-final loss to Germany on penalties sparked ugly scenes in Berlin with trouble breaking out on the touchlines and on the pitch. Officials and players of both sides got involved, the cause of the trouble lost amid the mayhem and confusion. Early in the fracas Germany defender Per Mertesacker received a nasty low to the groin from unused Argentina substitute Leandro Cufre.

FRINGS BANNED

Germany midfielder Torsten Frings was banned for the semi-final against Italy for his involvement in the Argentina melee. Frings was hit with a two-game ban, one of which was suspended, for punching Julio Cruz. Germany were angered as FIFA had previously said the German players would face no action.

ITALY GET KILLER GOAL

Italy were the stronger team in their quarter-final against Ukraine in Hamburg but with just a 1-0 lead after almost an hour, they were not having things all their own way. Ukraine rattled the woodwork through Maxim Kalinichenko but Italy broke quickly to settle the game. Luca Toni netted the decisive goal from a Francesco Totti cross but Ukraine claimed both he and Fabio Cannavaro were offside.

PORTUGAL'S ANTICS

Few tears outside of Portugal appeared to be shed for the elimination of Luiz Felipe Scolari's side by France in the semi-finals. The Portuguese were involved in stormy confrontations with Holland and England and caused further controversy by their willingness to go to ground too easily. Ronaldo was regarded as the chief culprit but others such as Helder Postiga and Pauleta were also guilty of diving at times.
