If Everton builds a retractable pitch, Liverpool becomes a market the size of London, and the NFL starts having regular season games at Goodison for a few years to test the waters, then I'll worry
@The binman chronicles. Till then, I think the 10 year deal up to 2028 is safe
But as I said in another post a while ago, I think Everton should be looking at a multi-purpose stadium with an artificial surface like ours, but rather than partnering with NFL partner with LiveNation or some other global entertainment company. Getting concerts and things going by the docks should be a money-spinner for the club.
