Manchester United defender Alexander Buttner is heading to Dynamo Moscow, according to the Russian club.

The Dutchman has played just 13 Premier League games and despite the arrival of his countryman Louis Van Gaal as manager, he is set to leave Old Trafford.

Dynamo say a contract has been agreed with the player, but there are still some "technical details" to be finalised.

Meanwhile, Arsenal have decided not to take up an option to buy back Mexican striker Carlos Vela.

The forward, who did not go to the World Cup, has agreed a new deal with Real Sociedad instead.
