Sunderland are reportedly frustrated with the Football Association's failure to make a quick decision regarding whether or not to appoint Sam Allardyce as the new England manager.

The Black Cats boss held talks with the governing body almost one week ago about becoming Roy Hodgson's successor.

The 68-year-old stepped down from his role less than an hour after England were knocked out of Euro 2016 at the last-16 stage by Iceland.

Sunderland made it clear via an official statement last week that they were unhappy that the FA's interest in Allardyce was not more discreet.

Now, according to PA, the North-East outfit are becoming increasingly exasperated by the fact that the FA's three-man hiring panel - technical director Dan Ashworth, chief executive Martin Glenn and vice-chairman David Gill - have not yet made a final decision.

It was recently reported that the FA will appoint a new manager next week, with USA boss Jurgen Klinsmann, Bournemouth coach Eddie Howe and Hull City's Steve Bruce also thought to be contenders.

Sunderland have not yet brought any new players to the club as targets are believed to be unwilling to commit until the manager's situation is made clear.
