One of the most used clichés in football is that all managers need time to settle into a club and change its fortunes. At Newcastle United, that very theory has been disproven by Alan Pardew.

While there can be endless arguments that certain managers have not been given enough time to settle before being axed by said club’s chairman, Mike Ashley’s patience with Pardew should have worn off 12 months ago.

Pundits and experts regularly spout that managers need to be given at least a year in the job before results begin hitting the heights expected by the club’s fans but it is also true that the men in charge can go stale.

And that is what Alan Pardew is at Newcastle United. Stale.

The performance the Magpies turned in at Southampton last weekend was unmistakably one by a team that had no faith in the manager. Throughout the second half, Pardew barely showed his face from the dugout, a clear sign that the pressure put on him by the travelling fans was getting to him.

After the game, Southampton manager Ronald Koeman revealed his side’s tactics. He instructed his side to get at Newcastle quickly in order to fully capitalise on the lack of confidence Pardew’s side had.

It clearly worked. A lackadaisical backpass from Fabricio Coloccini – one of the afternoon’s worst offenders – was pounced upon by Shane Long, who was unlucky to see his charge down fly just wide of the post.

Four minutes later, Newcastle’s luck was out as Graziano Pelle nodded in the opener, before tapping home a second before half-time.

Another cliché – and one of my personal bugbears – is that being 2-0 down is not the worst situation, as it means the losing team can attack without the fear of losing the game from a drawing position.

The game against Southampton was the perfect opportunity to prove this adage true but there was no reaction from the Magpies, who surrendered to a 4-0 defeat with miniscule resistance.

Half-time should have been a time where the manager should have been kicking boots and water bottles around the changing rooms and trying to instil some motivation into his beleaguered side.

But motivational skill is another of Pardew’s shortcomings. Newcastle’s record in the Tyne-Wear derby perfectly highlights as much. In a game where tactical nous is outweighed significantly by sheer will to win, Newcastle have surrendered bragging rights far too easily since Pardew’s appointment in 2010.

On Saturday, the Geordies welcome Hull City to St James’ Park and the atmosphere will no doubt be toxic. Banners and protests will dominate the city, leaving Pardew with nowhere – not even his dugout – to hide.

Dead man walking isn’t so much a cliché, more of a saying but certainly seems to be the most apt at Newcastle United at the minute.
