Manchester United manager Louis van Gaal has ordered a fence to be built around the Carrington training pitch to keep spies away from sessions at Carrington, according to reports.

Work on a green canvas permiter fence is set to start this week with most of his first-team squad away on international duty.

The Dutchman has already implemented numerous changes at the £60million Aon Training Complex, the perimter the latest addition, according to the Daily Mail.

He had floodlights installed so players can prepare for evening games, trees were planted to deflect wind and a pitch with identical dimensions to Old Trafford was laid - groundsmen are even told to cut the grass to the same length.

Security-conscious Van Gaal has also turned away workmen if they arrived at a time when his squad was training, while a road sometimes used as an overspill car park is off-limits during sessions, as people parking there can see the players in action.

Van Gaal has been criticised this week for his tactics during the defeat against Arsenal, with United players reported to be 'unhappy' that they didn't play on the counter at the Emirates, while Dutch legend Johan Cruyff also said that Van Gaal doesn't play 'dominating football'.

"He doesn't dominate. I like dominating football. Manchester doesn't play like that," Cruyff said.

"I don't think so," said Cruyff when asked if Van Gaal plays too cautiously, "but it's strange that against strong teams they've got good results and with weak teams they've had difficulties. That's a strange situation.

"But the results I think are second. The game is first. Money is very important but always second. In England they play different, everybody has their own style. A mix of styles is always good.

"The most important part are the fans, that people going home are happy. It's their time off and you should give them something to enjoy."
