Qatar organisers have claimed that there have been three deaths related to work on constructing stadiums, retracting comments earlier in the tournament by the Supreme Committee for Delivery and Legacy chief executive secretary general Hassan Al-Thawadi that "an estimated 400 to 500 migrant workers died as a result of work on projects related to the tournament."

Campiagners have rubbished this figure and accuse of Qatar of brushing the deaths of thousands of migrants under the carpet by classing them as occurring from "natural causes".

"There has to be an analysis, as independent an investigation as possible, and it's a responsibility we in football have to do that," Klaveness said, as reported by TV2.

"It's important here that we have a big commitment after the World Cup, to not just put this behind us now and actually have a proper assessment of what I call 'the elephant in the room'.

"Which in reality is the death toll and the number of injured, especially in the first years.

"Although it will create a lot of discussion, pressure and fuss, we, England, Germany, and many of the European federations, believe that it is necessary.

"Such an analysis is important to have a bridge to the future now, and for us to be able to move forward together in the football world."

Earlier this month FIFA said it was "deeply saddened" after a migrant worker died at a training base in Qatar.

A Filipino man, estimated to be in his early forties, died working at the Sealine Beach resort in a forklift truck accident.

The resort acted as a training base for the Saudi Arabian team during the tournament.

In response to journalists' questions about the incident earlier on in the tournament, chief executive of the Qatar 2022 World Cup Nasser Al Khater said: "Death is a natural part of life, whether it's at work, whether it's in your sleep.

"We're in the middle of a World Cup. 

"And we have a successful World Cup. 

"And this is something you want to talk about right now."

Klaveness added that "as a principal, it is incredibly important that the authorities in the country are responsible for the workers in the country.

"But this award was made on irresponsible grounds, with unacceptable consequences.

"There are compensation funds set up. 

"The truth is not so simple to understand or convey in an interview. 

"It's complex.

"That's why it's so important to have that process now, where you review and analyse, what really happened to the workers? What did it cost them, in the early years?

"We don't know how many migrant workers haven't gotten what they're entitled to, and we can't live with that."

Campaigners from Human Rights Watch, Amnesty International, FairSquare and Equidem have accused FIFA of "misleading" claims about compensation for migrant workers who suffered while working on the tournament and their families.

In October, FIFA's deputy secretary general Alasdair Bell claimed there had been "real tangible progress" in conditions for workers in the country.
