why wont it show the player name?

The output says streak is not a valid member of player please help.

hint=Instance.new("Hint") 
hint.Parent=workspace 
hint.Name="LargestStreak" 
while true do 
highestStreak=0 
p="" 
for _,player in pairs(game.Players:GetChildren()) do 
if player.streak.Value>highestStreak then 
p=player.Name 
highestStreak=player.streak.Value 
end 
end 
hint.Text=p.." has the biggest streak with the kill streak of "..highestStreak.."!" 
wait() 
end
