Arsenal will fly to Vietnam directly after they finish their game against the Indonesian Dream Team. With nothing planned for the airport as they arrive at 5am local time [although there will be 250 Arsenal fans waiting to greet them], the team will be whisked away for rest and recuperation at the Intercontinental Hotel in Hanoi which sits beside West Lake and was voted the most luxurious hotel in the city.
Arsenal will have a separate VIP area with private balconies and there will be 24 hour security. The hotel has also brought in a celebrity chef to cook for the club but his name has not been released. The chef will speak with Wenger and design the meals to his requirements for the squad.
As you can see from the images below, they certainly won’t be slumming it.
