Inter Milan boss Roberto Mancini says Mauro Icardi should've celebrated his goals in victory over Palermo.

Icardi appeared to be making a silent protest after a clash with fans last week in defeat to Sassuolo.

"In my opinion you should celebrate after a goal! I don't think he's unhappy, I assume it's a left-over from last Sunday. The fans cheered him, so it seems to be sorted out," said Mancini.

"Guarin played well, though at times he gets a bit stubborn with the ball and can lose his way. He's perfect as the deeper point of a midfield three, as he plays the ball well and has great power."
