Christian Pulisic dropped an absolute masterclass against Burnley on Saturday night.
Having quietly progressed through his first handful of Chelsea appearances, the floodgates well and truly opened when the American broke his duck for the Blues.
Pulisic crowned a superb individual run with a left-footed finish, doubled his bounty before half-time with a deflected strike and headed home from Mason Mount's cross for the treble.
And aside from becoming just the second American to score a hat-trick in the Premier League, it was also notable for being a 'perfect' treble as you can see from the descriptions above.
That, of course, means scoring with your right foot, left foot and your head.

You might think its not all that uncommon given the vast amount of hat-tricks that have been scored in England's top division, but - according to the Premier League - only 31 players have achieved the feat in 28 seasons.
And after Pulisic's superb performance, we decided to countdown those players and you'll be surprised to see that players like Wayne Rooney, Alan Shearer and Harry Kane miss out.
That, and the fact only three players have ever scored more than one 'perfect' hat-trick. Chit-chat aside, though, you can check out the full list of players down below:
