Inter star Antonio Cassano fears that it will be difficult to end Juventus' Serie A dominance next season if they strengthen their squad even further this summer.
The Turin powerhouse finished the 2012-13 season nine points clear of runners-up Napoli after pipping AC Milan to the Scudetto last term and Cassano believes that it will not be easy to close the gap again in the near future.
"Juventus are already a superb team and it looks like they are keen to sign some more top players this summer," Cassano told La Gazzetta dello Sport.
"It will be very difficult to beat them next season if their team becomes even stronger."
The 30-year-old then reflected on his performances in 2012-13 and stressed that he gave his all for Inter this term.
"I gave everything for the team this year and could not have done more."
Cassano netted eight goals in 28 Serie A appearances for Inter this season.
