Massimiliano Allegri feels Sami Khedira will be like a new signing for Juventus due to his return from injury.
Khedira has been restricted to six Serie A appearances this term but he came off the bench late as Juve beat AC Milan in Wednesday's Supercoppa Italiana in Jeddah.
Juve have been linked with a move for Arsenal midfielder Aaron Ramsey, but the Gunners are aiming to keep the Wales international until his contract expires at the end of the season.
And even though Juve face a busy schedule as they compete for honours both domestically and in Europe, Allegri does not expect to make significant additions to his squad this month.
