Inter will face Juventus in the Guinness International Champions Cup competition on August 6.
"We hope to do the best we can and use these defeats as a lesson. It's something I've expected from my first day here, that Inter would become competitive again.
"We need to try and give everything, playing in a convincing way. In terms of doing things automatically we're improving.
"It's certainly not easy for a new Coach to start from scratch."
