Wales coach Robert Page admitted his team had fallen well below the standards they set for themselves as defeat to Iran put them on the brink of World Cup elimination.

Page refused to use Wayne Hennessey’s red card – only the third for a goalkeeper in World Cup finals history – as an excuse for the defeat, and said Carlos Queiroz’s team were well worth their win.

Iran hit both posts and had a goal disallowed before they finally took the lead in the 98th minute through substitute Roozbeh Cheshmi’s long-range strike, with Ramin Rezaeian adding a breakaway second three minutes later.

Gareth Bale and Aaron Ramsey, so often the architects of Wales’ successes down the years, were both disappointing and they now need a victory over England next Tuesday to have any hope of reaching the knockout stages.

Page even appeared to refer to the England game as Wales’ “final” match of the tournament, underlining how difficult the road ahead is for the Dragons from here.

Page said.

“This is a hard one to take,”

“I’ve said to them before every game: ‘Go and show the world what you show us every day,’ and that is not a true reflection of that team.

“They got their true rewards today, they deserved that defeat. We fell well below the standards that got us to the World Cup, if we’d met those standards we’d have been alright. And if you do that in top competitions, you get punished.”

“We want to finish the competition on a high. It’s out of our hands for going through, but we want to finish with a good performance and a win. We’re low at the moment, but we’ll get them back up tomorrow for a tough game to finish with.”

Hennessey was initially shown a yellow card after he raced out of his goal and clattered into Iran’s Porto forward Mehdi Taremi, but referee Mario Escobar was advised to review the decision, and returned from the monitor brandishing a red card.

The challenge was reckless and high, regardless of whether there was cover behind him.

The win for Iran means their match against the United States – which would always have been highly charged given the political history between the nations – could now be winner-takes-all for a place in the last 16.

Queiroz felt too much external pressure was placed on his players ahead of the England game.

The team have become a political lightning rod for the turmoil in Iran, with those who are pro-regime criticising them for not singing the anthem before the England match and protesters attacking them for not doing enough to highlight the plight of women in the country.
