Shrimpers could net Hornet front-man
20-year-old Theo Robinson impressed during a loan spell at Roots Hall but he still has two years to run on his contract with the Hornets.
Robinson scored seven times for Southend during his loan spell and admits his future depends on his current employers.
"It's too early to know what's going to happen and I certainly don't know at this stage," he told Southend's official website. "The most important thing to me is just that I'm playing first-team football again.
"Going to Southend gave me another taste of that which I enjoyed but I need to speak to Watford and also my agent to see what they have in mind for me.
"I really enjoyed my time with Southend. It was a good loan spell, though, and the team did well too. I'd be quite happy to go back but I'm really not sure what will happen."
