Cape Town - FA Cup holders Arsenal have announced a 27-man squad for the Barclays Asia Trophy in Singapore.
Arsène Wenger will be without Copa America participants Alexis Sanchez and David Ospina, while Serge Gnabry is also resting after the European Under-21 Championship.
Danny Welbeck and Tomas Rosicky will stay in England to recover from minor injuries but Calum Chambers will travel to Singapore, as will France Under-17 international Jeff Reine-Adelaide, who joined the club from Lens.
"Calum has decided to shorten his holiday and come back on Friday," Wenger told Arsenal.com.
"He didn’t play in the under-21s and needs preparations.
"Welbeck isn’t completely recovered from the problem he had [at the end of last season]. He’s not back in full training so he will stay behind.
"Rosicky will stay back because he got a small injury at his last game against Iceland with Czech Republic.
"Ospina is on holiday until July 27 and Alexis is on holiday until August 3. Serge Gnabry is on holiday after playing with the under-21s. He’s back on July 20."
