Smoke without fire

The phrase has meaning “no smoke without fire”. AKA David Jones’ story in his autobiography.
I use the phrase here after learning that UEFA has charged the Serbia and England Football Associations following the argy bargy at the end of the Under-21’s football match between the countries.
Whilst, not there, from the comfort of my armchair, I would plead provocation in the sense of clear racism from the Serbian supporters, mischievous behaviour by the same (akin to that we used to see regularly in British football before our act was cleaned up somewhat) and a dubious reaction to affairs on the pitch post-final whistle, from the home team’s players and management.
In that sense, the cause or both smoke and fire appeared to be from Serbia. But England has ‘previous’ and in a final fracas UEFA appears to have taken the easy – not necessary correct action – and penalised both.
