The star played hunky gardener John Rowland in the first series of the hit, and regularly made appearances as the lover of Eva Longoria's character Gabrielle Solis.
And Metcalfe admits he's keen to return for one last time during the show's upcoming eighth and final season.
He tells the Press Association, ""I would definitely be open to it. It seems appropriate, seeing as I was part of the birth and the initial success of the show, to bring me back for the final season.
""But we'll see if there's interest there. I do think it's the right time. It was a very successful show and it'll be forever ingrained in the public consciousness.""
