Former England and Liverpool captain Steven Gerrard has described St George's Park as having an atmosphere that fails to bring out the best in players.
Gerrard says the Football Association's £105m national football centre needs to be more player friendly.
The 330-acre St George's Park site in Burton, Staffordshire, opened in 2012 as a base for all 24 England teams at various levels.
In an interview with Rio Ferdinand for a BT Sport programme, Gerrard said he thinks the complex needs a golf course to help overcome the "shyness" in the England squad.
"It's an unbelievable site but they need to be a bit more realistic around it," he said. "They need to make it a little bit friendlier for the players.
"It's a top place to train and prepare but away from training pitch and the games, it can be boring. We need to create that atmosphere where England players are desperate to get away and do well."
"When you get to England, you want to have your lunch and go to bed and keep away from everyone because there's a shyness. There needs to be an England atmosphere when you turn up and you know each other, you want to be with each other."
