But Jenkins firmly believes that joining a club like Wigan, who finished 11th in the Premier League last season, would not represent an upward step in his career.
"They've got more funds available because of the Premier League handouts, so they would probably pay more wages and the manager would have a bigger budget to work with," added Jenkins.
"But looking at it from my point of view I don't see it as a step up at all.
"We've got far more potential for a greater support than Wigan would ever have and I firmly believe Roberto should be looking to the top six in the Premier League or the top teams around the world if and when he decides to move on.
"He's young enough and he's got plenty of time on his side to do that."
Swansea midfielder Joe Allen has benefited more than most from Martinez's preferred style of play, where sound technique takes precedent over physical attributes.
The diminutive midfielder says it would be a huge blow to the club if they were to lose their inspirational manager.
"I'm sure everyone at Swansea would definitely want to keep him," said the 19-year-old Allen.
"I owe a lot of my success to him. He's the reason I've pushed on this season."
