Juventus GM Beppe Marotta admits they will buy in January.

Manchester City left-back Aleksander Kolarov and Sao Paulo defender Rhodolfo are among his targets.

"We're bridging the gaps. It starts with a project, but if there's any deficiencies, you make the corrections," said Marotta.

"The championship? Our goal is to get back in the top three in the Champions League ... But thinking of the title is in our culture."
