Arsenal manager Mikel Arteta says Ben White is in "really good shape" after returning to action with the Gunners.
The defender then travelled to the UAE for Arsenal's friendly with AC Milan and played the first half of Tuesday's 2-1 win in Dubai.
"I'm very pleased. Everybody has been giving him a lot of support and love, which is what he needed," said Arteta.
"We are delighted to have him back and have him in really good shape."
White did not feature in England's opening two World Cup matches and missed their final group game against Wales through illness, and the following day the Football Association announced he had left the squad.
