With only nine weeks until England's opening World Cup qualifier against Slovakia, a three-
man committee of Glenn, FA technical director Dan Ashworth and forer Manchester United chief executive David Gill are prepared to wait if that is what it takes to get the best man.
Wenger is out of contract at Arsenal next summer and Glenn said:
"Yes, we would be willing to have a caretaker-manager for such an important decision.
"Even if somebody is coming to the end of the contract in a year – it is a possibility, of course. "If you said, 'This person is an absolute shoo-in, can you wait?'
Then we are well-placed with an interim solution. Otherwise you might get a few interim solutions – a few managers to come and help.
"It is such an important decision. We have got to get the right person. To wait a few months, if that is what we had to do, would be the right decision."
Southgate is in charge of the England Under-21 team and Glenn responded knowingly when asked if there was somebody who
could step into the void if a decision is not made by September.
"We'd like to get one for the first World Cup qualifier (in Slovakia on September 4) but if we won't we have an interim plan in mind,"
Glenn said. "We are not talking about names today but it would be a pretty obvious one to pick.
