Antonio Rudiger and Kalidou koulibaly were both strongly linked with Chelsea last summer, and as we approach another summer transfer window, the duo have been linked with Chelsea yet again.

Antonio Rudiger was subjected to racial taunts from Lazio fans in the Rome derby on Wednesday, and reports have it that it has left the 23-year-old distraught. According to the Daily Express, Chelsea are on alert over Antonio Rudiger’s availability this summer with reports suggesting he wants to leave Roma.

Chelsea and Koulibaly are also back in the rumours. According to the Daily Star, Chelsea want to sign Napoli’s Kalidou Koulibaly as a replacement for John Terry.

Antonio Conte has made the 6ft 5ins France-born Senegal international centre-back his top target this summer but he will cost Chelsea up to £60m, Daily Star reports.

We’d see how these rumours pan out in the coming weeks and months. But it gets me wondering if we really need another centre-back, with Andreas Christensen coming back next season, and we currently have Gary Cahill, David Luiz, Cesar Azpilicueta and Kurt Zouma, not forgetting the recently recalled Nathan Ake.
