ROBIN VAN PERSIE has given his Manchester United colleagues a prior warning that Louis Van Gaal's training sessions are likely to be very tough.

Van Gaal was appointed by the Red Devils on a three-year deal and will take charge after the World Cup.
United finished a disappointing seventh and ended the season trophyless, something that the Old Trafford faithful aren't used to.
Van Persie has admitted he's relishing working under Van Gaal, but has warned his team-mates they will be worked into the ground during 'enormously intense' 75-minute training sessions.
"Every training session is very intense. He is on our backs every minute," Van Persie told The Sun.

"There is no space to relax, he demands full focus.
"We work very hard for a maximum 1.15 hour, never longer. But these 75 minutes are enormously intense."
Van Persie will skipper Holland at the World Cup finals.
