Sporting director Txiki Begiristain said a new body would be set-up to enforce club rules which will be made up of himself, coach Frank Rijkaard, president Joan Laporta and five players.

"Sometimes the three can't cover everything so we'll create a committee of five players who will be a group that hold sway over the dressing room," he told Catalan daily newspaper El Periodico.

"But that doesn't mean that we'll assign a policeman on each player.

"The main idea is that everyone turns up in the morning in prime condition and to allow players to know exactly what is permitted and what isn't."

Late night partying by players like Brazil's Ronaldinho and Cameroon international Samuel Eto'o fuelled media storms last season and were blamed for distracting the team who finished second to bitter rivals Real Madrid in the league.

"We're expecting an immediate reaction," said Begiristain, who stressed players are expected to eat dinner at home the night before a match.

Barcelona goalkeeper Victor Valdes welcomed the move, telling reporters "this type of internal organ could be good for everyone, the players, the technical staff and everyone involved in the dressing room."

Twenty-five Barcelona players head to Scotland on Monday for a six-day training camp at St Andrews.

The team will face Dundee United in a friendly at Tannadice on Thursday and Hearts at Murrayfield on Saturday and will then tour China and Japan at the beginning of August.

Argentina's Gaby Milito and Lionel Messi and Mexico's Rafa Marquez are being rested after taking part in their national teams in the Copa America and will not take part in the training camp and tour of Asia, the club said on its web site.

Barcelona captain Carles Puyol and Icelandic striker Eidur Gudjohnsen will also stay behind as both players have knee injuries.
