Roma are inviting offers for Antonio Rudiger.
The Germany defender came close to joining Chelsea last summer before a knee injury scuppered the deal.
Now fully fit, BILD says Rudiger is available this summer for £34m amid reported interest from Chelsea, Manchester City and Bayern Munich.
Pep Guardiola reportedly sees the German centre-back as a long-term successor to injury prone Vincent Kompany at the heart of the City defence.
