I think there are two ways of looking at it, as a player and as an asset.
The player piece is subjective, some rate him others say he would never have cut it - that is subjective. you can make an argument either way.
As an asset he gone from 1.9 mill to 6-10 mill, in six months, in any walk of life in any job if you decrease your exposure to that asset and it jumps in value that much - its poor judgement.
5million in football is about the same as 50p to us lot.
