Special ability or advance in quality?

thanks. of course I am talking here about investment of green boosters. otherwise, it wont be possible to achieve that speed of development... unfortunately.
this 18yo player that I would like to use in following seasons as well, so I guess developing Aerial ability would be beneficial... I am just not sure if it will improve the job he does
Reading the forum, i found out that aerial defender is very valuable for DC, but not sure if its really true. thats why posted the thread here...

Areial defenders are good... they get good ratings and also perform well. Investing in one should be worth it
