You will hear a lot in the coming weeks and months about legacy. That there isn't one. That if UK Athletics leave the London Stadium to football, the Olympic bequest has been squandered.
Don't believe a word of it. What is about to happen now, is what should have happened more than a decade ago. The Olympic Stadium was never viable as the home of athletics.
There was never going to be legacy in one or two track events a year, plus the odd pop concert. London has Wembley for concerts. It's where Live Aid was held.
