Zokora told his manager Martin Jol he was off balance

Foy gave a spot-kick when Didier Zokora fell, supposedly under a challenge from Pedro Mendes, but even Spurs boss Martin Jol said there "was no contact".

Redknapp said Foy told him: "I'm sorry, Harry, I've made a big mistake."

But the Pompey boss added: "He didn't make a mistake on purpose. Referees need help out there."

Redknapp used the incident to revive football's perennial debate about the use of video technology during matches.

"I saw from the big screen that it was no way a penalty about 10 seconds before it was taken. So why can't the fourth official, who is wired up to the referee, have a monitor by the side of the pitch and tell the ref what really happened?

"The boy dived and the penalty has cost us dear. People say diving has become too frequent but it has always happened.

"Surely we should use the technology to stamp it out and put things right. It was not much different to the Ben Thatcher incident a few weeks ago when he was only booked for that terrible challenge on Pedro.

"We have got to do something about things like this. The referee Dermot Gallagher wanted to help us after his mistake at Manchester City and I'm sure this referee does now as well. But nobody can. I certainly cannot do anything about it."

Jol defended his player afterwards, insisting Zokora was "off balance".

"You can see him going in all the time and sometimes he does look off-balance," said Jol.

"But this was not a normal dive. In fact, I don't think I've seen a situation like this in this country before.

"I can understand Harry Redknapp being upset but I've been upset myself over a couple of things in the last two years.
