The Magpies are 'not that good a team' and will regret seeing their boss go, according to the pundit.
The former Premier League midfielder's controversial claims suggest Pardew did an 'unbelievable job' at Newcastle and that they are 'not that good a team.'
And Newcastle will struggled without the Palace-bound 53-year-old, according to Merson.
“Probably because he was a southerner,” he said on Sky Sports, as quoted by the Newcastle Evening Chronicle.
“Dennis Wise was the same. He pulled up trees there, they are not that good a team. Those fans will realise when he’s gone what an unbelievable job he did. If they were in a relegation battle now it wouldn’t have shocked me one iota.
“He has done an unbelievable job there and those fans, come March, will be sitting there thinking ‘Cor, he was a good manager he was’. We’ve seen it a million times. Alan Curbishley at Charlton.”
Fellow Sky Sports pundit Matt Le Tissier did not agree, however...
“He was a little bit fortunate to be in the job in my opinion. There was a long period of results where a lot of other managers wouldn’t have survived."
