Queens Park Rangers manager Mark Hughes does not think it is realistic for Harry Redknapp to combine roles in charge of Tottenham and England.
White Hart Lane boss Redknapp is the runaway favourite to be named permanent successor to Fabio Capello, who on Wednesday night sensationally resigned.
But Tottenham are likely to want to keep hold of their current manager and there has been a suggestion Redknapp could fill both tasks during Euro 2012.
However, having in 2004 remained Wales manager for two matches while also taking charge of Blackburn, Hughes believes that would be unfeasible.
"I used to change my opinion in that regard," Hughes said at a press conference ahead of QPR's Saturday fixture against former club Blackburn.
"Sometimes I thought it was possible. I think I probably said that prior to getting a club job.
"I think I did the role part-time and I found it quite difficult.
"I think it is a little bit unrealistic to expect to be able to do a high-level club job and a national team.
"But if you get it right, the England job is one of the best national jobs in world football.
"I am sure there will be a lot of candidates putting their hands up, both English, British and foreign. We'll have to wait and see what happens."
On Thursday lunchtime, the Football Association confirmed Stuart Pearce will take caretaker charge of England for the game against Holland later in February.
