Inter boss Walter Mazzarri concedes that Juventus and former club Napoli will be title contenders in 2013-14.
The Old Lady have won the last two championships and have been busy on the transfer market in an effort to strengthen even more.
“Juventus were already strong, very strong,” the ex-Sampdoria and Livorno tactician told La Domenica Sportiva. “And now they've strengthened further.
“They're even more complete. They had a fantastic season last time out. They did well in the Champions League up to a certain point and they'll be able to hold their own next year too.”
The Bianconeri have made two notable acquisitions in attack with the capture of Carlos Tevez from Manchester City and Athletic Bilbao’s Fernando Llorente.
“They are two great players who bolster an already excellent squad,” Mazzarri added.
Asked about Napoli, whom he left last month, Mazzarri believes they will remain competitive with Rafa Benitez now in charge.
“They came second last season after four years of growth and I think they can only improve,” Mazzarri noted.
“As a club they're in good shape and there's every chance of them succeeding. But Napoli is the past for me – I want to talk about Inter now.”
