I understand why Tottenham are reluctant to sell Harry Kane to another English club.Theyknow very well that he is a good player and selling to another englisg club will only mean that they are empowering their rivals. Chelsea do not think this way, that is why they have made the mistake of selling Kovacic to Manchester City. Kovacic will be brought back to his best by Pep, and he will become a very good player for Manchester City that can pair with Rodri in their midfield. Chelsea made a mistake.
