At the National Stadium in Singapore, the first Spanish club to compete in the International Champions Cup (ICC).
In terms of manpower, Atletico did not have best forces in the ICC 2018 from main reason contribution in the World Cup knockout round in 2018. Simeone has had to put most of the squad in their squad for the World Cup 2018 and not be able to rejoin the summer tour. On the contrary, Arsenal are almost always full of the best individuals, even Mesut Ozil from Russia is ready to play.
Atletico's Griezmann, Lemar, Hernandez, Vrsaljko, Luis, Costa, Saul, Koke, Godin and Gimenez are still in the post-World Cup standings. Arsenal, Nacho, Xhaka and rookie Torreira are also absent for similar reasons.
Simeone will be enforced to field an inexperienced line-up as he's without plenty of key players due to their World Cup commitments.
So this is the opportunity for Arsenal to find a victory over Atletico Madrid. Sure the players want to prove their ability in the eyes of the coach to find a place in the squad next season. Unai Emery also wants Arsenal fans to see the positive changes after Arsene Wenger.
Having said that I see typical scenario visible in past edition of Champions League, Atletico warming up, only played against selection of Nigeria so this is truly first preseason training camp's fixture will play what they used to play, welcome Gunners on their half. From other side Arsenal boys with motivation to improve to new manager will play offensive like they always do. Corners should follow to offensive actions of English club.
