SOUTHEND United chairman Ron Martin insists striker Charlie Kelman is not for sale.

Championship club Swansea City have tabled an undisclosed offer for the 18-year-old.

But Martin will not be cashing in.

He said: “Charlie isn’t for sale, definitely not.”

Swansea, who reached the Championship play-offs last term, have a link with MLS side DC United.

And if Kelman did get snapped up by the Swans it is believed he would be heading to the American outfit on loan.
