Nowell scored either side of a penalty try, while Jared Payne finished things off with a superb fourth – as the Lions displayed some superb attacking rugby.
But they were just as sound defensively, limiting the Chiefs to two Stephen Donald penalties in their victory.
And just days away from their first match against the All Blacks, the Lions performance whipped social media into a frenzy as fans and former players all praised their excellent performance.

With Jack Nowell and Jared Payne finishing off superb moves, a lot of emphasis was placed on the way the Lions fired in attack.
Good win for the @lionsofficial boys! Good set piece & a few good tries too. 👍🏽🦁 #chiefsvlions

It takes time to build a team, but Scott Hastings knows that the Lions are creating a great side.

Jack Nowell stood out on the wing, and Lewis Moody was suitably impressed.

Having twice gone close against the Blues, this time Jared Payne got over the line, and celebrated with his son after. Payne junior didn’t appear to be enjoying it quite as much as his old man!
James Haskell enjoyed a fine game and afterwards he caught up with opposite number Mitchell Brown to swap shirts.
Meanwhile Courtney Lawes showed off his lineout prowess, looks like he enjoyed this picture of him in action!
