Gana is a way flies in the face of the Soucek on the wane debate, we've got 3 possibly four high end seasons out of him.
On the age and transfer thing, i feel people ca be very dogmatic about it, its not an absolute rule, sure you make investments for the future, but there is also a necessity to develop those players with experience around them and remaining competitive int the league - you need experience for that.
You need Barrys' Gana's and JT's - maybe even Souceks.
You cant have too much of one thng without balancing it with the other.
