I'm sure the strategy is to win the CL sooner than later and to provide Pep with sufficiently good signings to do it while he is still here. He might fail to win it but we won't treat him as a stepping stone whose task is to leave a strong team for the next manager. We will sign a ready made CB, not one with bags of potential who may or may not come good in 2-3 years. And among those who have enough CL experience and are quick, Koulibaly is regarded as one of the best. I don't know whether and how much we want Koulibaly. But I can see why we may be after him.
