Rome:Inter Milan booked an Italian Cup quarter-final date with AS Roma but they made heavy weather of beating a Genoa side 3-1 on Wednesday after their opponents were reduced to 10 men in the 20th minute.
Inter - who have faced Roma in the last four Italian Cup finals with both sides winning it twice - progressed eventually thanks to extra-time goals by Argentinian midfielder Esteban Cambiasso - who was being watched by national coach Diego Maradona - and Swedish star Zlatan Ibrahimovic.
Unpredictable Brazilian striker Adriano had put Inter ahead with 15 minutes remaining but a mistake by Argentinian defender Walter Samuel let in Genoa's captain Marco Rossi to level four minutes later.
Adriano had a curate's egg of a match having originally won the penalty in the 20th minute that saw Genoa's Giuseppe Biava sent-off - Adriano, though, had his penalty saved by the outstanding Genoa goalkeeper Alessio Scarpi.
Time and time again Scarpi saved his side, but eventually something had to give and the barrel-chested Adriano headed home from a cross by Maxwell in the 75th minute - only for Rossi to benefit from Samuel's mistake minutes later.
However, Genoa's resistance eventually wilted 10 minutes into extra-time as first Cambiasso turned in an Ibrahimovic shot that had been saved by Scarpi and then three minutes later Ibrahimovic wrapped it up.
