Internazionale coach Roberto Mancini admits experienced players are needed if his side is to fight for the title next season.
The Nerazzurri's hopes of qualifying for next season's Europa League were dented as they fell to a 2-1 defeat at home against Juventus.
But Mancini insists this will not affect the way Internazionale will work during the summer transfer window.
"It wasn't just about mistakes today," Mancini told Sky Sport Italy.
"Mistakes can see you lose games, but also win. We played well in the first half, we shouldn't have ended with a 1-0 scoreline but two or three goals ahead. When you have so many chances are you fail to take them you then pay for it.
"Qualifying for next season's Europa League is now difficult but this doesn't affect our future. We have to create something important and we're working to do it.
"We need experienced players who can improve the technical level of the squad. They would also help the young players because when a young player plays alongside a great champion, he has to improve his level.
"[What is needed to fight for the title next season?] The difference between us and the other teams is not that big.
"At the moment Juventus is the greatest but things could change during a campaign."
