The 21-year-old, whose 24 goals helped the Shrimpers win promotion, has been tipped to leave Roots Hall this summer.

But deputy chairman Geoffrey King said: "He is not for sale. I had two calls within 10 minutes saying offers of �500,000 and �750,000 had been made.

"At that rate, it could have reached �1m. Neither offer had been made and, as I say, he is not for sale."

Eastwood himself has ruled out joining Forest, saying: "If I did leave, it would be for a Premiership or Championship side."
