Input: We understand why Raheem Sterling has left Liverpool. He wants an upgrade: in the standard of his team-mates, the potential for achievement, quite probably in salary, too. So, yes, we get it. What is harder to fathom is why Manchester City have been so determined to sign him. Do they think Sterling will change, simply by swapping a red shirt for sky blue? What leads Manchester City to think he will treat their club with any more respect than Liverpool, if circumstances change? Sterling’s behaviour in recent weeks should be a warning sign. Having put up with Carlos Tevez taking a mid-season sabbatical, why would they wish to go through that turmoil again?Manchester City have £49m bid for Liverpool's Raheem Sterling acceptedSterling has angled for a move and has skipped training and a tourManuel Pellegrini has placed faith in Sterling but should not expect it backMo Farah was right to snub Andy Vernon handshake at Diamond LeagueSerena Williams is possibly the greatest female athlete of all timeREAD: The most expensive signings by British clubs after SterlingREAD: Sterling's record Manchester City move will leave QPR £9m richer
