Cricket's Panel of Elite Umpires is in need of urgent review, according to Simon Taufel Tony Hill has been at the centre of several umpiring controversies this Ashes series. ICC Umpire Performance and Training Manager Simon Taufel believes the current structure of cricket's Panel of Elite Umpires is in need of urgent review after more controversy in the fourth Ashes Test at Durham. Eight of the world's top 12 umpires currently come from either Australia or England, making them ineligible to officiate in any Ashes Test according to ICC rules. Speaking exclusively to FOX SPORTS News, Taufel - who never officiated in Test cricket's greatest battle during his 12-year umpiring career because of the rule - said that all cricketing nations are obliged to produce elite umpires. "Recently I went to the MCC Cowdrey Lecture and I said, "Look, umpiring is everybody's business and we all have a responsibility to produce quality match officials," he said. Simon Taufel joins us for a LIVE chat here from 1pm EST, ask him a question by leaving a comment, or ask on Twitter with the hashtag #AskTaufel. It is incumbent on all of the other home boards to produce more quality match officials. We definitely need more depth. Pressure has mounted on all four umpires who have stood during the Ashes series - Aleem Dar, Kumar Dharmasena, Marais Erasmus and Tony Hill - after a horror run of on and off-field decisions. Most recently it has been Hill who has earned the ire of players, commentators and fans for his questionable calls in Durham. Hill's standout blunder came on day two when he gave Australian opener Chris Rogers out caught behind, only for the batsman to successfully review the decision after he clearly missed the ball. In the process of the review, third umpire Marais Erasmus found that Rogers could, however, have been dismissed lbw, but was not given out as lbw was not part of Hill's original decision. The decision caused mass confusion for players and spectators, a situation Taufel is keen to avoid in the future. When I sit down I look at playing conditions that have been drafted, I try and get those playing conditions as close to the laws of cricket because people generally understand the laws of cricket. The less that we write going over the top ... the simpler things become. But with two days and plenty of crucial decisions remaining in the fourth Test, Taufel admitted that Hill would be feeling the pinch. I feel for any match official who doesn't get it right on the day at a crucial time. A lot of work and preparation does go in to our performances," he said. It's fair to say that Tony has had the lion's share of appeals in this match as well and a couple haven't gone his way. Umpiring is a confidence game as well and that's why it is very important we don't get involved mid-match here with Tony and start to pre-judge or pre-determine certain things.
