Data Store Problem?

I was making an autosave/autoload thing to my place. It saves leaderstats. Unfortunately, it doesn't work.The stats don't load. Here are my scripts:

Leaderstats/autoload:

local datastore = game:GetService("DataStoreService"):GetDataStore("AlienData")

game.Players.PlayerAdded:connect(function(player)

local leaderstats = Instance.new("IntValue")
leaderstats.Name = "leaderstats"
leaderstats.Parent = player

local wins = Instance.new("IntValue")
wins.Name = "Wins"
wins.Parent = leaderstats

-- GUN RANK

local points = Instance.new("IntValue")
points.Name = "Points"
points.Parent = leaderstats


local key = "player_"..player.userId

local savedvalues = datastore:GetAsync("key")

if savedvalues then
    wins.value = savedvalues[1]
    points.Value = savedvalues[2]

else

    local valuestosave = {wins.Value, points.Value} 
    datastore:SetAsync(key, valuestosave) 

    end
end)

Here is the onplayerleaving/autosave:

local datastore = game:GetService("DataStoreService"):GetDataStore("AlienData")

game.Players.PlayerRemoving:connect(function(player)

    local key = "player_"..player.userId
    local valuestosave = {player.leaderstats.Wins.Value, player.leaderstats.Points.Value}

    datastore:SetAsync(key, valuestosave)

end)
