Leonardo Bonucci insists he will work hard to 'shift the balance'

in AC Milan's favour next season after completing a shock switch

from Serie A champions Juventus.

The 30-year-old Italy defender, who had been linked with Chelsea

and Manchester City, unexpectedly called time on his successful

seven-year spell with Juve to move to San Siro last Friday.

Bonucci is thus far the standout capture in a summer of

aggressive transfer activity by Milan.

The Rossoneri are looking to land the Scudetto for the first

time since 2011 by investing heavily in the first-team squad.

Ricardo Rodriguez, Lucas Biglia, Mateo Musacchio and

Andre Silva are among the other expensive recruits but

Rossoneri fans appear to be most excited about 70-time

Italy international Bonucci.

And on Monday he promised to advance the Milan mission

in 2017-18, and wrote a caption on his Instagram page.

Bonucci stunned fans by opting to leave the Italian champions

to join their Serie A rivals

'Some supporters asked me if I'll be able to shift the balance...

I will work to make it, fighting with more hunger than ever,' he wrote.

The former Inter Milan player has also been handed the

captain's armband for a campaign which will see the Rossoneri

compete in the Europa League following a sixth-placed

finish last term.

Now owned by Chinese businessman Li Yonghong, Milan

are reportedly eyeing big-money deals for Torino hitman

Andrea Belotti and Pierre-Emerick Aubameyang of

Borussia Dortmund this month.
