I was just pointing out that the article that tweet linked to had no new information. Everyone's automatically put on that entry list unless you specifically withdraw, which he still could as it get closer.
True, but Switzerland wasn’t on the entry list for the ATP Cup last year when Fed was healthy. Both Stan and Fed withdrew in December. Since they didn’t do that this year, it makes it possible they’ll play.
Consider every other team except Russia has one good/great player and one spare tire as a team. Switzerland could go far with two great players:
Serbia: Djokovic/Lajovic
Spain: Nadal/Bautista
Austria:Thiem/Novak
Russia: Medvedev/Rublev
Switzerland: Federer/Wawrinka
Greece: Tsitsipas/Perolarakis
Germany: Zverev/Struff
Argentina: Schwartzman/Pella
Italy: Berrettini/Fognini
Japan: Nishikori/Nishioka
France: Monfils/Paire
Australia: Wild Card
Canada (alternates): Shapovalov/Raonic
