Newcastle hero Ferdinand: Campbell can go into his 40s
Ferdinand told the Evening Chronicle: “There is a saying: ‘Form is temporary and class is permanent’. I think that applies to Sol in a big way.
“I played with Sol when he was 24 or 25 and he is just a class act.
“It was a great signing for Newcastle and he will prove that over the course of the season now he is fully fit and looks ready.
“It did not surprise me he came on against Manchester City and did so well.
“I know people were saying he was a little bit overweight when he came in, but he looks the part now. There were those pictures which people probably saw and made their own judgements.
“Sol was between clubs, he was getting married and he had other issues going on in his life, so it was really not the end of the world if he was not quite right at that time.
“He went some way to answering those criticisms coming up against one of the best sides in the league in Manchester City and playing the way he did.
“That criticism also neglects the fact Sol is naturally quite a fit guy and he applies himself in the right way. He is a top professional and he does things the right way.”
