[2491] How to re-route to default children using nested routes ?

Hi everyone and HNY, For my website I'm trying to re-route people hitting the 'equipe' router-link (going to /equipe) in my navbar to the children nested page /equipe/2018, with this folder structure:

However I can't see how to do this, as I tried to extend routes but this replace the component and the parent, and reroute the "hard-way" with

created:
  function () {
    if (this.$route.fullPath == "/equipe") {
      this.$router.push("/equipe" + "/2018")
    }
  }

does some strange bugs.

How can I keep the link to /equipe but redirecting everyone coming straight to this to /equipe/2018? Thanks a lot!
