AS Roma maestro Francesco Totti is set to miss the Roma derby against Lazio, on Wednesday, because of an ankle injury. Manager Luciano Spalletti has announced his squad for the match and it didn't include the name of the 30-year old skipper. Totti was injured against Sporting Lisbon last week and missed AC Milan crucial clash last week-end. Mirko Vucinic is set to replace the "Prince" in the front line and hopes he could score to fit in his boot.
