SelectNodes in HtmlAgilityPack always return null

I'm trying to get data from this site: https://www.hltv.org/results, and it doesnt work. SelectNodes always returns null, I've tried using xpath, full xpath and so on and different things other than HtmlAgilityPack. Maybe its not the HtmlAgilityPack maybe the problem is in the tags. Please take a look at the code and view also the tags to see if if i copied it right:

    HtmlWeb web = new HtmlWeb();
    var doc = web.Load("https://www.hltv.org/results");
    var teams = doc.DocumentNode.SelectNodes("//*[@class='team team-won']");

Please Help, Thanks!
