Pretty much the most appealing point you've made...when was the last wonderkid that Chelsea has bought or produced within the last couple of years? Kakuta is not at that level yet, sorry to burst bubbles here. In 4 years time I want a player still young on our team that has the experience and postture of a world class player (Ronaldo at Utd, Messi at Barca) ..NOT players that are nearing mid 30s and looking for temporary replacements every time we fall short. The rebuilding process takes time to implement and if we don't seize this opportunity to sign a player with such heavy upside such as Neymar, I can only imagine us paying up to double for some next player in the near future, and we all know how effective it is putting a new player mid way through the season is to the current squad.
