Hayden is surplus to requirements at St James’ Park and had appeared set to complete a loan move to Sheffield Wednesday.
The move to Hillsborough has collapsed though and now Hayden has another option to consider before the window shuts.
Standard Liege want to tempt Hayden to move to Belgium and the Newcastle man is considering what to do.
Hayden is likely to want to make sure he is playing regularly over the course of the campaign and joining Standard Liege could appeal.
Standard Liege however have had a poor start to the new season in Belgium.
They have picked up just two points from their opening five league games.
Standard Liege will be hoping that Hayden can be convinced to make the switch to Belgium before the window shuts.
