Why won't this script save player data?

So i've made this script that's suppose to remember how many stages the player has completed and how many trophies he's collected but it won't work even tho it doesn't show any errors.If any1 has any ideas or suggestions i'm all ears.

Thanks for your time

data = game:GetService('DataStoreService'):GetDataStore('MobbyProgres')

game.Players.PlayerAdded:connect(function(p) -- Player joins

local stats = Instance.new ("IntValue",p)
    stats.Name = "leaderstats"

    local stage = Instance.new("IntValue", stats)
    stage.Name = "Stage"
    stage.Value = 1

    local trophies = Instance.new("IntValue",stats)
    trophies.Name = "TrophiesFound"
    trophies.Value = 0

    key = 'Pinfo_'..p.userId 


    if data:GetAsync(key) ~= nil then 

        stage.Value = data:GetAsync(key)[1]
        trophies.Value = data:GetAsync(key)[2]  

    else 
        data:SetAsync(key, {1,0}) 

    end
end)

game.Players.PlayerRemoving:connect(function(p) 
    key = 'Pinfo_'..p.userId 
    local save = {p.leaderstats.stage.Value, p.leaderstats.trophies.Value}
    data:SetAsync(key, save) 
end)
