Bought him for 61 millions and retrained him to be a AML. I use him as an inside forward, total freedom of creativity and also changing places with Rooney from time to time... and it's quite the partnership!
Neymar is a better poacher than Rooney, so quite often Rooney goes to AML and gives lots of assists to Neymar score.
Neymar also runs for best player in the world since his first year in the English Premier. Although I payed a little too much for him, the thing is to better have him in your team than playing against him.
