Croatia fielded their best team, which is what a team captain does when they want a win, while France did not.
With his current ranking, there's no way that Tsonga should've been on that team while Monfils and Simon (two players who have repeatedly beaten Cilic, Monfils never having lost to Cilic or Coric) were left off the team.
Lucas Pouille, who clinched the tie for France last year, was thrown in at the last minute after not even being named to the team.
France/Noah was simply messy. At least he's stepping down, which a good thing.
Although with the future of Davis Cup being so uncertain, I don't know what any of this is leading into.
Nevertheless, congratulations to the Croatian Davis Cup team for winning the last Davis Cup as we know it, lol.
