The Argentine seemingly can't wait to line-up alongside his new team-mate as the new season approaches.
The two defenders are just a part of Milan's big money revamp this summer and Musacchio says that he is happy with how things have gone so far.
He told 'Milan TV': 'I feel very good, I'm really happy. This is a new team and we're all just getting to know each other.
'These games are important to get to know each other, training sessions are crucial but in the games it's more intense.
'We're working to become a great team and the club is working well from that point of view. We're training hard to have a great season.
'We're working on the defence and in Italy, like in the rest of the world, the defence is very important. Teams are built from the back and we're training for a good year.'
Though the former Villarreal man retained some special praise for his new defensive colleague.
'Bonucci is one of the best defenders in the world, and if I play beside him it'll make everything easier. I'm very happy to play with him,' he enthused.
Will the pair form a solid partnership this season?
