Roy Keane has questioned Roy Hodgson's appointment of Gary Neville to his England backroom staff.
The former Manchester United defender was handed the role following a season working as a pundit for Sky Sports, in which he has been praised for his insight.
Keane, who has had stints in charge of Sunderland and Ipswich Town, believes that "sitting in a studio" is very different from coaching, despite having the relevant UEFA badges.
"Everyone says it's a good appointment, but I'd say let's wait and see," said Keane, Neville's former Red Devils teammate. "Gary hasn't done any coaching before. I know he has the qualifications, but sitting in a studio talking about teams is very different.
"I'm pretty sure if England have a decent tournament, or a decent couple of years, Roy Hodgson and his staff will get the praise. But if they don't get the results, the manager will get criticism and people will no doubt be criticising Gary too.
"Gary's a decent guy and played at a decent level, but that doesn't guarantee you success. At Old Trafford he always had his say, but wasn't as influential in the dressing room as people think. He wasn't calling the shots – far from it."
Neville, who has 85 caps for his country, retired from football in 2011.
