"In discussion with the player and our medical team, we have chose to continue with an individual training programme for Thiago", head coach Carlo Ancelotti said.
Arsene Wenger thought it was food poisoning but the club's medical team have since insisted it is a stomach bug unconnected to anything the players may have eaten. Bayern, in very hot conditions that saw Sead Kolasinac come off having been sick, started the far better of the teams, and took the lead after 8 minutes from the spot. "I don't know (what they may have eaten)", Wenger said at a post-match press conference in Shanghai reported on the club's official website.
Next up for Arsenal is a meeting with Premier League champions Chelsea in the Bird's Nest in Beijing on Saturday.
"We are here to prepare", continued Wenger.
The Gunners keeper had one of his finest games against Bayern in the 2012 Champions League final and was on top form in this ICC friendly.
"In Australia, it was more about the offensive game; [against Bayern] we had to defend as well.
It was an interesting game for us because we had to dig deep and I think we will benefit from it".
"Has it got other advantages?"
Antonio Conte's side will play out their first proper pre-season game of the summer at the Bird's Nest Stadium.
The German worldwide suffered a dip in form in front of goal last season as he found the back of the net just five times in 29 Bundesliga appearances - 15 fewer than in the 2015/16 campaign. The bonding is easier because we live together for two weeks.
"Of course we can lose to Real Madrid because that is a great team".
