(REUTERS) - AC Milan ruthlessly extinguished any remote prospect of a footballing fairytale as they hammered third-tier Alessandria 5-0 in the second leg of their Italian Cup semi-final on Tuesday.

Milan can now scent their first Cup win in 13 years as they added to their first-leg 1-0 win with a thrashing of their Lega Pro visitors, featuring doubles from Jeremy Menez and Alessio Romagnoli, to wrap up the 6-0 aggregate win.

Alessandria brought more than 15,000 fans to the San Siro stadium for their big night but reality quickly bit when the five-time winners went one up after 20 minutes.

Frenchman Menez, back in form after spending much of the season injured, controlled the ball on his chest before smashing home a superb opener.

Romagnoli turned in a half-volley soon afterwards before Menez made it 3-0 by halftime with his clinically-taken second.

The rout continued near the end when Romagnoli had a fourth goal confirmed by goal-line technology and Mario Balotelli scored in the dying seconds.

Milan will now play either Juventus or Inter in the final, with Juve in seeming command, holding a 3-0 advantage from the first leg before the return in Milan on Wednesday.
