Jul.11 (GMM) Lewis Hamilton is not yet the finished article, according to his father and manager.

Following the torrents of criticism preceding the British grand prix, and the 23-year-old McLaren driver's subsequent dominant win, Anthony Hamilton seems surprised by the level of expectation on his charge's shoulders in 2008.

"He's going to make mistakes, he's only 23," he told his local newspaper The Comet.

"He's been in this business - what - one and a half years? He's learning but (last Sunday) he showed a master class," Hamilton Snr added.
