Widnes coach Denis Betts was full of praise for New Zealand winger Patrick Ah Van after watching his side rally from 14 points down to secure their first win at Bradford for 23 years.
Ah Van claimed two tries in three four minutes to end the Vikings' run of five games without a win and seal a 32-28 success over his former side.
His first was a spectacular 80m break from deep in his own half while his second needed a marvellous finish, diving in at the corner as two Bulls defenders tried to barge him into touch.
"Some of the tries he's scored, he's up there with some of the best wingers in the world," said Betts.
"He's a great guy to have in the team - the other boys love him and with his quality of finishing, he's always likely to score tries.
"He has his socks rolled down around his ankles and looks half the time not to be bothered but he knows how to finish."
"We've shown character last three or four weeks but it's probably stood us in good stead - losing so many close games in recent weeks. They had to respond and showed lots of character and the right work ethic.
Betts' opposite number Francis Cummins was frustrated to see the Buls fail to capitalise on their first-half advantage having taken a 18-4 lead.
"To go from being so dominant to throwing the game away in the second half, I can't describe how disappointed I am," he said.
"We gave them nearly every thing they got and good luck to them - they carried on and won the game.
"We are edgy at the moment and we were trying to kill off the game.
"We tried coming up with big plays to kill the game off whereas building pressure with different kicks would probably have been better."
