The FA and every other nation who bid for 2018 should sue FIFA for the cost of their bid process, being as we now know from the horses mouth (as was obviously suspected) that Russia was already a done deal, and all bids were, from the bidding nations point of view, a complete waste of time and money.
The FIFA delegates got all their lovely jollies out of it, being ferried around the various venues, being wined and dined and treated like royalty as the FA toadied up to them for votes. Now that the entire process has been revealed by Blatter himself to have already been rigged before a vote was even cast, any lawyer worth his salt should be able to get tens of millions out of that stinking cartel of an organisation, and hopefully bankrupt them in the process.
FIFA won't be able to pay right now, money is too tight. But we can get it in nine years.
