England and South Africa enter day two of the Test with controversy over the use of technology refusing to die down.

The two teams were at loggerheads over disputed catches on the opening day of the second Test at Headingley which South Africa closed 102 runs in arrears with seven wickets intact.

And they also had contrasting views on a referrals system for disputed decisions for this series with England objecting to players making the calls on when to challenge.

The biggest flashpoint came deep into Friday's evening's final session when Hashim Amla was told to remain on the pitch by the South Africans after England captain Michael Vaughan claimed a diving catch at mid-off off the bowling of Andrew Flintoff.

When Amla initially took Vaughan's word, South Africa were effectively 76 for four.

"I have long advocated the use of technology," said South Africa coach Mickey Arthur.

"Funnily enough we wanted the referrals system - because it was going to be trialled in this series - and England were against it.

"I don't think they wanted it trialled in a series that's important but for me if we can get the correct decision at any time that has got to be good for the game.

"That is all we're asking. The referral system takes away the grey area."

England coach Peter Moores explained the home team's position, however, after the International Cricket Council pinpointed this campaign for the increased use of technology.

"People say we didn't want referrals," said Moores. "We support referrals but what we didn't want was players to do the referring.

"We thought the umpires should be taking the responsibility and we made it pretty clear that certain things should be referred and certain things shouldn't. If that was in place we would support it."

Arthur, meanwhile, suggested England got their comeuppance after Vaughan addressed AB de Villiers at lunch following a claimed catch in the slips off Andrew Strauss which was shown to have been grounded.

"It's fair to say that AB took a lot of criticism at lunchtime from some of the England players," said Arthur. "From Michael Vaughan himself.

"It's amazing there's a lady up there called Mother Cricket, who doesn't sleep - and it came back to haunt Michael Vaughan later in the day.

"AB is a really good, honest guy who plays the game in the right spirit - and he would never for one minute consider claiming a catch that he didn't think was out.

"He thought it had gone from one hand to the other. It clearly didn't and it looked pretty ugly on the telly.

"He felt really bad about it, and that is the nature of AB."

Arthur gesticulated to Amla to remain on the field until the umpires had sought clarification from third official Richard Kettleborough - if a batsman leaves he is deemed out.

"I'm 100% sure it bounced," said Arthur. "When it actually happened we thought it looked 50/50.

"Luckily the replay came up before Hash was off the ground, and I could get out there and tell him to stand.

"It is my business. Hashim Amla is probably the most polite guy in the world, a very disciplined boy. He wouldn't have questioned anything.

"I felt I needed to tell one of our key batters, a guy in form, to stay on the ground so that the correct decision could be made."

Had England claimed that fourth success then they might have held claim to the whip hand heading into this morning's resumption.

But Moores tried to play down the heated atmosphere between the sides when he said: "If your team are shouting to you to stay then you have to stay and wait to see what the umpire says.

"The only thing I would say is that Michael thought he had caught it clean, so obviously claimed the catch.

"But when they were in the huddle there was a big commotion because it was shown on the big screen and it was he who said to the umpires they should refer it. He still thinks it was a clean catch."
