Absolutely tragic. Sounds so cliche, but there are no words to describe how brave this boy was. So, so sad. Thoughts are with his family.
And also, the cynical tweets are shocking and disgusting. They're really going to abuse those who pay respects to a 6-year old boy becuase he supported United? Pathetic.
Also would like to mention Harry Mosely, an 11-year old who had a similar conidition and who died a few days ago as well. R.I.P to both of them.
