ROME — AC Milan and Inter need to switch their focus to Sunday's Milan derby in a hurry following lengthy midweek trips to eastern Europe.

Milan stifled a Zenit St. Petersburg comeback for a 3-2 win in an action-packed Champions League match in Russia on Wednesday, while Inter was facing Neftchi in a Europa League game in Baku, Azerbaijan, on Thursday.

After slow starts to the season, both clubs are starting to find their form.

Milan teenager Stephen El Shaarawy has scored five goals in his last four matches, while Diego Milito and Antonio Cassano are forming a potent attack tandem for Inter.

While Inter is tied for third, four points behind co-leaders Juventus and Napoli, Milan is in the bottom half of the standings, nine points behind.
