Former France, Liverpool and Paris Saint-Germain defender Mamadou Sakho announced his retirement on Monday aged 35.

The 25-year-old did not complete the match against Crystal Palace in the English Premier League (EPL), while his club feared at first that he had suffered a ligament injury to his knee which could have sidelined the player for more than six months.

France defender Mamadou Sakho said his teammates are burning with rage, not because they have anything personal against the Germans, their FIFA World Cup quarterfinal opponents, but because they are still feeling the anger and desperation after barely qualifying for the tournament in Brazil.

In front of a raucous crowd at the Stade de France, Les Bleus overturned a two-goal first-leg deficit and qualified for the World Cup finals, beating Ukraine 3-0.

Nigeria striker Victor Moses was signed from Premier League rivals Chelsea on a season-long loan while France international Mamadou Sakho and Portuguese centre-back Tiago Ilori arrived at Anfield on permanent deals.

Arsenal and Manchester United are expected to be busy in the transfer market Monday. English clubs are already close to spending 500 million pounds ($775 million) in the summer window.
