Como and Inter Milan drew 0-0 in a cagey Italian Cup semi-final first leg on Tuesday in which they managed just one shot on target between them.
Inter manager Cristian Chivu made 10 changes from the team that beat Genoa on Saturday to go 10 points clear in Serie A.
Cesc Fabregas' Como largely dominated the match but squandered a series of promising positions.
Winger Mergim Vojvoda missed at least three clear first-half chances while full-back Alex Valle spurned a good chance just after half-time.
In the other semi-final, Lazio host Atalanta on Wednesday.
