Returning Inter Milan coach Roberto Mancini admits his side will have to improve quickly if they are to climb the Serie A table.

The former Manchester City and Galatasaray manager guided the Nerazzurri to three Serie A titles and two Coppa Italia trophies during his first stint with the club, but he has returned to a side struggling in ninth place in the table.

Mancini faces a baptism of fire after replacing Walter Mazzarri at the helm earlier this month, with the Italian tactician facing a Milan derby and a showdown with Scudetto hopefuls Roma in his first two fixtures.

The 49-year-old accepts the ties against AC Milan and the Giallorossi will prove stern tests for his Inter side, but he is excited by the challenge.

“No meeting would have been simple in the Serie A but I have to say that starting with Milan and Roma is fascinating and difficult,” he told the Gazzetta dello Sport.

Mancini insists no targets have been set in terms of securing titles for Inter but he is eager to see a quick improvement in terms of results and performances after returning to the Milan club.

He added: “For our objectives, there is no set date for an Inter title but improvements need to be quick.”

Inter are 2.72 to secure victory over their city rivals at the San Siro on Sunday, the Rossoneri, who are the home side for the fixture, are available at 2.60 and a draw is available at 3.15.
