The Swans have slipped to 12th in the Premier League but are only three points ahead of rivals Cardiff, who are second from bottom.
The two clubs meet at the Liberty Stadium in a crucial south-Wales derby on Saturday.
"The bigger picture as always is winning a Premier League match and it so happens this week we are playing Cardiff," he told BBC Sport.
"Winning the match I can assure you is the most important thing for both teams."
Added Jenkins: "When you end up losing matches, when everything is so tight at the bottom of the Premier League, you get rumours and you get stories.
"We have had them for many weeks. If we win everything is fine. If we lose it's not."
