Paul Parker has played down the impact of Newcastle’s £12m signing of Kieran Trippier from Atletico Madrid.

The ex-Manchester United, Chelsea and England defender suggested that right-backs don’t win matches, and that the Magpies – now boosted by super-rich Saudi owners – need “five new players to stay up”.

He told The Betfred Football Show: “Defensively, Newcastle are atrocious. The centre-halves are just not good enough.”

Parker, who won the FA Cup with United when they beat Chelsea 4-0 in 1994, picked out three FA Cup Third Round ties this weekend which could throw up a shock.

Although he expects Newcastle and Arsenal to get through their assignments with Cambridge and Nottingham Forest respectively, he highlights the two games as potential banana skins for the Premier League sides – while he reckons the big one will be Championship side Hull beating Everton to pile the pressure on Toffees boss Rafa Benitez.

Parker reminisced about the oldest knockout cup competition in the world, saying that in his bygone years the FA Cup final was a must-watch.

“It was the biggest day of the season,” he said. “But in those days you didn’t really know that much about the players as individuals. You didn’t know their personalities – but now the personalities of footballers are like solid wood.”

The 57-year-old was absolutely scathing in his assessment of former club Manchester United ahead of the Third Round tie between the Reds and Aston Villa at Old Trafford on Monday.

He described recent performances as “woeful,” adding: “A toolbox is about tools in the box, and these players are just not good enough.

“They want to walk about in Manchester city centre and say they play for Manchester United, not that they play for Manchester United and are winning things. They aren’t trying.

“Manchester United have got a relegation midfield… they are that bad.

“They’ve got names, but not what matters most – heart, passion and courage. The club is not in a good place.”

Parker reckons United could well lose out to his favourites Arsenal for a top-four Premier League finish – and in the Championship he backs Bournemouth and another of his former clubs, QPR, to win the two automatic promotion places.
