The Rossoblu have agreed a deal with the Bianconeri for the right-back that will allow them to enter into a co-ownership agreement at the end of the season, should they see fit
The Italy international spent the second half of last season at Catania, but had been heavily linked with the Rossoblu in recent weeks and his move to the Dall'Ara was finally confirmed on Thursday evening.
"Bologna FC 1909 announces that it has reached an agreement with Juventus for the transfer of defender Marco Motta on a temporary basis, with a right to redeem half of the player's registration," a statement on the club's website read.
Motta initially arrived in Turin on loan from Udinese in 2010 before sealing a permanent transfer the following summer.
However, he was quickly deemed surplus to requirements by new coach Antonio Conte and did not make a single appearance in Serie A for the Old Lady last season before being farmed out to Catania.
