In addition to World Cup qualifying, Chelsea have three players competing in the quarter-finals of the UEFA Nations League, including a first senior call-up for Filip Jorgensen.
It is set to be an interesting international break, with new managers naming their first squads for both England and Belgium as World Cup qualifying gets under way in Europe, while it is already in full swing in South America. On top of that, the Nations League knockout stages begin, with eight sides looking to book their place at the 2025 finals.
You can see a full breakdown of the players called up and the games they will be hoping to feature in below.
We will be updating this article in the coming days as more players are called up.
