In this essay
Personally, I prefer not to use this kind of statement
Some support while others think that huge amount should be spent on young children to train them as sportsperson.
I think this is a little too similar to the prompt. Instead of proponing both point of view in the incipit, you could try doing so:
In the first paragraph express only your point of view and motivate it the second, as you have done.
Then you could use an expression like "some people could believe that investing the money in events is better" and use the third paragraph.
Maybe you could try to modify a little the conclusion, to explain in a more convincing manner why your way of thinking is the right one.
I hope I was clear enough, I'm still not very at ease with english...
I hope you find my opinion useful!
