It is disgraceful that Nantes are asking for some form of payment, show some f****** humility and empathy to the sensitive situation.
Like people say, this poor lad has not even been found, so no chance to pay last respects. At least leave it till then and show respect to the family who are only now beginning to grieve.
As mentioned, this will surely be down to an insurance issue, which I can imagine will take an eternity to sort out, if indeed Cardiff were covered!
