Inter fell to Udinese on Saturday.
“Today we're here with an unhappy result," Icardi admitted.
“But we're celebrating Christmas together, to celebrate the journey we've made together so far.
“Sassuolo have been playing well for a few years, we know that, it's difficult against them because they've been playing together for several years and they'll definitely play a good match.
“We'll do everything we can to start the new year well and start again straight away."
