I bought Neymar for 17M with wolves.. and then after 3 seasons inter came knocking .. and offered me 60M.. I couldn't resist the offer.. but I did include a 40M buy-back clause which they accepted then sold him.. I've never bought him back until now..
Problem is that there isn't any better alternative to Neymar at the moment. I have a regen lined up to replace Neymar but he needs a few more seasons to get to the same level. I'll probably keep him until his mid-late 20s and sell him for a hefty profit to La Liga, would hate having to play against in EPL.
