You may be right - this is the article that mentions it but there isn't a direct quote stating why they didn't want him:Dan:6775233 said:I don't know how true that is. Judging an eight year old on their size is beyond stupid and I highly doubt everyone in Chelsea's academy is 6'3" and stacked - two that I can think of in Ryan Bertrand and Liam Bridcutt can't be much more than 5'9".

Given they could have had him, and didn't, whatever their reasons were, for their sake, I hope they've improved their selection process.
