Inter Milan coach Andrea Stramaccioni feels they'll improve after introducing their three new additions in defeat to Siena.
Ezequiel Schelotto and Zdravko Kuzmanovic made their debuts from the start, while Mateo Kovacic came on for the second half.
"There's no point talking about the new buys, as they have very few training sessions behind them and I don't like discussing individuals after a defeat," said Stramaccioni.
"Kovacic is a player of great quality and made his debut in a difficult game, but showed confidence and character. He is a valuable investment.
"It was a bad performance and we deserved the defeat. In these cases either you cry and despair or you try to get back on track. I prefer the latter."
