Arsenal and Manchester United are on red alert over Palermo defender Simon Kjaer's intentions of moving to England.

The Denmark international is a favorite of United boss Sir Alex Ferguson, while Arsene Wenger, the Arsenal manager, is also keen as he seeks to clearout his ageing defence.

Kjaer's agent, former Middlesbrough striker, Mikkel Beck said: "I have encouraged him to try the Premier League."

The young centre-half's Palermo deal carries a £10 million buyout clause.
