Southend United boss Phil Brown is convinced Jozy Altidore can succeed at Sunderland.

Brown worked with Altidore at Hull City.

He told the Daily Star Sunday: "We took over a loan he was on from ­Villarreal in Spain. He was only 19 - a pup - but he had potential.

"He has started to fulfil that potential. He did well in a good league in Holland. For a big lad, he wasn't as good in the air as you would have expected. It was something he had to work on.

"But he was gifted. He was a beast in terms of his ­physique. He had pace and good technical ability.

"I would say £6m is not a bad price for a 23-year-old with Altidore's attributes.

"If I was signing him now for the Premier League, I'd be looking for him to get me double figures in terms of goals this season - then 20 in his second year."
