King's trio of strikes at home to West Ham United, the second by a Cherries player in the PL after Callum Wilson, against the same opponents last season, was the first hat-trick by a Norwegian since John Carew in February 2008.
Carew and King are two of six Norwegians to score a Premier League hat-trick, although only two have done so more than once.
In joining his compatriots, King's three goals helped to consolidate Norway's place in the top five of most hat-tricks scored by nation, moving two clear of Ivory Coast, Nigeria, Scotland and Spain.

But King's first career Premier League treble also lifted Norway to within one of second place in terms of most hat-tricks scored by different players from a nation.
Indeed should one of Adama Diomande, Havard Nordtveit, Markus Henriksen and Omar Elabdellaoui score a hat-trick then England would be the only nation to have more hat-trick scorers in the Premier League's history than Norway.
|Nation||Players with hat-tricks|
|Ivory Coast, Wales||5|
|Italy, Nigeria, Spain||5|
King has some way to go if he is to get close to the Premier League's record hat-trick scorer, Alan Shearer, who managed 11 in his career, two more than Robbie Fowler and three more than Thierry Henry and Michael Owen.
