Ajax coach Frank de Boer is under consideration at West Ham United.

The Mail on Sunday says it is understood there has been some form of contact with De Boer's people for a second time even though he has indicated he would stay with the Dutch champions.

But for all his reputation which previously put him in the frame for jobs at Tottenham and Liverpool, Hammers chief Sullivan has concerns the success in Holland with the country's top club does not necessarily mean De Boer is battle ready for the Premier League.

The club have set a two week deadline to make an appointment.
