The FIH president Leandro Negre gave a thumbs-up to the security arrangements made for the World Cup.

"I am very happy with the security arrangements. It is of the highest level," Negre said.

The FIH chief, who arrived here last night for the World Cup starting Sunday, said the organisers have done their best and everyone should leave it to the security experts.

"With all the international players around, you cannot afford to take chances. Players' safety is very importance for us. You have to go by the police because they are in the best position to advise you on security," he said.

The run-up to the World Cup has been marred by security concerns after a militant group issued a terror threat against foreign players visiting India. It prompted New Zealand striker Simon Child to pull out at the last minute.

The organisers have put in place a water-tight security system, restricting even the media from covering the training sessions at the Major Dhyan Chand National Stadium here, the main venue for the 12-team event.

However, the England hockey squad is leaving for New Delhi today to participate in the World Cup starting Sunday but security arrangements in the Indian capital are still a concern for the players, according to a report.

England's Hockey performance director David Faulkner acknowledged there were apprehensions among the players related to security and that they were in contact with the British High Commission in Delhi regarding the arrangements, 'The Times' reported.

"The excitement of playing in a World Cup has been dented and it is unsettling," Faulkner was quoted as saying by the newspaper.

"The safety and security of the England squad remains our priority and we are in daily contact with the British High Commission in Delhi regarding security arrangements. We fully intend to go to the World Cup," Faulkner said.

Head coach Jason Lee said specialist security personnel will be attached 24 hours a day at the team hotel as well as at the bus and stadium.

"We'll be stuck in the hotel a lot more than normal and I guess we'll be suffering from cabin fever. But the players can amuse themselves with all the technology and games around and who knows, some of them might even read a book," Lee said.

The England players, who open their campaign in the mega event against Australia on Sunday, will reach New Delhi from Doha where they had a pre-tournament training camp.
