Several Arsenal players featured for their national teams on Friday. While you may not care about how they performed - after all, Arsenal don't get extra points for things that happen in World Cup qualifiers - you probably care about the health of all the players involved. So I'll cover that in addition to the actual performances. Spoiler alert: pretty much everything is fine.
Jack Wilshere and Theo Walcott both started in a 4-0 win over Moldova. Reports were that Wilshere worked well with Steven Gerrard and Frank Lampard, but also took a little bit of a beating. Theo created a goal for Rickie Lambert by having a powerful shot saved. Other than that, not a lot to write home about. Wilshere was subbed off after 60 minutes. Neither was injured.
Olivier Giroud started and played the full 90 after an injury scare, as did Bacary Sagna and Laurent Koscielny. It was a horrifying 0-0 draw against Georgia, by all accounts. None were injured.
Aaron Ramsey played the full match and scored the only Welsh goal in a 2-1 loss, drawing a penalty and converting it himself. He was not injured.
Tomas Rosicky played the full match and scored the only Czech goal in a 2-1 loss to Macedonia, on a deflected long shot. He was not injured.
Wojciech Szczesny and Lukasz Fabianski were both on the bench for a 1-1 draw against Montenegro. Neither was injured.
Nacho Monreal spent the whole game on the bench, but Santi Cazorla came on for the last ten minutes of a 2-0 win over Finland. He didn't have time to have an effect on the game. Neither was injured.
Possible free agent striker target Ciprian Marica scored and assisted in a 3-0 win over Hungary. He came off after 80 minutes. As far as I can tell, he was not injured.
