Arsenal manager Arsene Wenger revealed that midfielders Aaron Ramsey and Alexis Sanchez will feature in Scandinavia at the end of the week.
The Gunners will face Viking FK and Manchester City respectively at the Viking Stadion and the Ullevi Stadium before preparing their Premier League opener against Liverpool.
All players involved at the Euro 2016 Championship and the Copa America will soon join the rest of the squad as the Frenchman will finally have an almost full squad to choose from.
"Not all of [the international players will be back]," Wenger told Arsenal Player.
"But [Aaron] Ramsey will be involved, Sanchez will be involved.
"The latest players coming back will not be involved, that's [Mesut] Ozil, [Olivier] Giroud and [Laurent] Koscielny, they are the last ones and I don't think they will be involved on the tour on Thursday, but all the others will."
