Switzerland have expelled Palermo defender Michel Morganella from their Olympics squad for offensive tweets.

Morganella was part of the Swiss team that was defeated by South Korea 2-1 on Sunday.

After the game he posted on Twitter: "I am going to batter the Koreans, burn them all... bunch of 'trisos'."

Trisos is a French slang word for people with Down's Syndrome.

Swiss newspaper Le Matin published the tweets from the players account but the tweets have since been deleted following the furore.
