Southgate defends decision to go public on White's England absence
White was not part of the England squad announced on Thursday for friendlies against Brazil and Belgium this month, despite a string of good performances for Arsenal in recent weeks.
Southgate said the 26-year-old, who has not featured for England since leaving the World Cup camp in November 2022, had asked not to be considered.
"I don't think it would be right not to state the situation we're in," he told reporters.
"We've explained to Arsenal we were going to do that. And if you make a decision like that, you do have to stand by it."
Southgate said that while he does not have huge credibility "there would be none if I didn't pick him on form".
England will host Brazil on March 23rd and Belgium three days later at Wembley Stadium.
