But while Sharp's future remains up in the air, they look certain to land Eastwood after the former Grays player declared his intention to quit Roots Hall.
"I want to move on. I've had three really good years but having had a taste of the Championship, it's where I want to stay," Eastwood told the Southend Echo.
"I'm an ambitious person and my dream is to play in the Premiership. League One is a long way from there and that's why I want go.
"It's got nothing to do with the money, I just want to play at the highest level possible.
"I know Wolves have had a bid for me turned down but I would be interested in going there. I think they will go up next season so it would be a good move for me. "
