Cole Palmer, bought for £40 million (US$54 million) three years ago, aged 21, and now worth at least three times that amount, would be the stand-out example of the buy-them-young strategy bearing fruit. Then there is the case of Jorrel Hato, little known beyond Dutch shores when he signed a seven-year contract with Chelsea last year. The defender joined from Ajax, where he made his senior debut at 16 and captained the first team aged 17. Fans in Hong Kong will get the chance to see the 20-year-old against Juventus on Wednesday, when Kai Tak Stadium stages the second and final match of this year’s Hong Kong Football Festival. Jorrel Hato played all 90 minutes of Chelsea’s 1-0 FA Cup final defeat by Manchester City.
