​Real Madrid’s summer rebuild is not over yet.Despite already reinforcing Jose Mourinho’s squad with four high-profile arrivals, the club is still planning further business before the transfer window closes.AdvertisementAdvertisementAdvertisementIn fact, according to Defensa Central, citing journalist Tomas Gonzalez-Martin, Mourinho has asked for another centre-back and remains keen to add greater creativity in midfield, while club president Florentino Perez continues to keep alive his long-standing ambition of signing Michael Olise.The report suggests Madrid are preparing for another active few weeks, although any major additions are expected to depend on departures from the current squad.Real Madrid have already addressed several positions this summer with the arrivals of Marc Cucurella, Ibrahima Konate, Denzel Dumfries and Bernardo Silva, but Mourinho believes the squad still requires further adjustments.AdvertisementAdvertisementAdvertisementOne of his priorities remains central defence.Mourinho has requested a defender and a midfielder.
