Denis Betts hailed Widnes' historic 35-28 win at St Helens as their best since returning to Super League.
The Vikings, who suffered a 62-0 defeat in the reverse fixture last season,
ended a 16-match losing run against Saints that stretched back to 1994, stunning Nathan Brown's side with a six-try show.
Betts said: "It feels like our best performance back in Super League. We got a real good thumping here last year and it's never easy to win at Saints.
"We showed plenty of desire but it was disappointing to concede two late tries, we wanted to keep them below 20 points."
Betts paid special tribute to Jack Owens, who scored two tries and four goals, as well as skipper Jon Clarke.
"Jack was fantastic at full-back and has really matured over the last few weeks," Betts added.
"It's a big stage here and he did a lot of work and that's why I took him off to give Danny Craven a run.
"When Rhys Hanbury is fit, we will have some real exciting ball runners at the back who can ignite our side.
"Jon Clarke was outstanding and doesn't get the plaudits he deserves. He's a model professional and playing as well as ever."
Saints trailed 34-18 until snatching late tries from Tony Puletua and Alex Walmsley - the latter converted by Tommy Makinson - and Brown admitted his side were stuck in a rut following their fifth successive defeat.
"We are low in confidence at the moment," he said. "It was disappointing to see our response after having a try disallowed when we led 12-6.
"We defended well for a long time but our resolve was not quite good enough to keep us in the contest.
"Some of our younger players are outshining more experienced ones and the big picture for the club looks good.
"We are missing our injured players and being without our number one and nine (Jonny Lomax and James Roby) is very important."
