Watford are worried they will be forced to make a second managerial change of the season to try to fight off the threat of relegation from the Premier League.

Quique Sánchez Flores was reappointed to succeed Javi Gracia only in September, but Watford slumped back to the bottom of the Premier League at the weekend.

They have only won once in the league under Flores and Saturday’s 3-0 defeat by Burnley demonstrated that there has been little improvement in their defence.

Flores was asked to return to try to improve the defence, along with results, but is yet to achieve either, and Watford now face a key game against fellow relegation strugglers Southampton.

Watford are desperate for Flores to turn the situation around, but there is a growing fear that they will have to make another change if results do not quickly improve.

Telegraph Sport has been told that it is extremely unlikely that Watford would turn to a firefighter in the mould of Sam Allardyce or Tony Pulis to get them out of trouble.
