For a moment I thought you meant Ajax, the team that was almost invincible in 2019 where they demolished every team in the world.
If you track the records from Willem 2, last time they won with Ajax in Amsterdam.
In Current season we have too many wired results in European Leagues because of Covid-19 as last night Top ranked Manchester United lost to bottom ranked Sheffield United in really good game as they was dominant but fail to convert their chances into goals but on other side Sheffield United was really on target and achieve their best of this season with this result even surely they are going to relegate but this is really amazing from them against top ranked team in away match.
