Former Liverpool goalkeeper Bruce Grobbelaar has lashed out at current Reds manager Rafa Benitez's rotation policy, saying many retired players agree that it must stop. The Spanish tactician's future looked bleak after he was heavily criticised for resting key players in Saturday's humiliating FA Cup defeat by Barnsley.

But he received some respite on Tuesday when they beat Inter Milan 2-0 in the UEFA Champions League.

Nevertheless Grobbelaar, who won 13 medals in 13 seasons at Liverpool, said a lot of former players were concerned by Liverpool's slide this season. They are 19 points behind Premier League leaders Arsenal, and are out of the FA Cup and Carling Cup.

"The ex-players are all hurt - Ian Rush, Sammy Lee, Gary Gillespie, John Aldridge, Alan Kennedy, David Johnson. When we are together, that's what we talk about," he told the Straits Times newspaper.

"The rotation policy simply has to stop. Bob Paisley once said 'football is a simple game made complicated by players and coaches'. It's all about picking the best team and letting them get on with it in the park."

Grobbelaar, in Singapore as a television pundit, added that American owners Tom Hicks and George Gillett were right to make an approach to Jurgen Klinsmann earlier this season. "In business, if the manager is doing badly, the big bosses have every right to interview potential candidates to take over," he said.

"Why can't football be the same? Liverpool are not getting results. It's right for the Americans to talk to Klinsmann."

Following victory over Inter Milan, Benitez was quick to seize on the chance to defend his rotation policy. "I rotate because I want to win. I have explained several times that you need to change players if you want to keep them all fresh," he said.
