David Willey has claimed that he will never play as well as he did in Northamptonshire's 102-run victory over Surrey in the Friends Life Twenty20 final.
The all-rounder struck 60 from 27 balls before recording figures of 4-9 with the ball as he completed a memorable triumph with a hat-trick at Edgbaston.
"I'm really pleased. To be honest I didn't think we'd won and I thought there was another wicket needed," he told Sky Sports News.
"This is once in a lifetime. I will probably never play like this again so I should probably quit while I'm ahead.
"The guys are playing exceptional cricket, we enjoy each other's company and we are all contributing."
Northamptonshire had earlier beaten Essex to set up the final with Surrey.
