It seems that Pep ranks this player very high so I wouldn't be suprised if we sign him. This will for sure mean that Marquez has to leave. I wouldn't cry if he did actually.
I would actually love it if Marquez leaves!! If we sign Caceres it would be great, our defensive lineup would look very impressive next season.
The only problem could be with the backup of the FBs (Sylvinho is not getting any younger I guess one more season and that's it, Oleguer does not fill me with confidence whenever he steps foot on the pitch and I would welcome any replacements).
The mixture of young and experienced defenders is going to be amazing, Pique and Caceres can learn a lot from Puyi and Milito.
