ST PETERSBURG, Russia (Reuters) - Russia striker Pavel Pogrebnyak scored twice as Zenit St Petersburg stunned favourites Bayern Munich 4-0 on Thursday to reach the UEFA Cup final.

Zenit, who won the semi-final tie 5-1 on aggregate against four times European champions Bayern, will meet either Fiorentina or Rangers in the May 14 final at the City of Manchester Stadium in England.

Pogrebnyak, however, will miss the final through suspension after picking up a yellow card in the second half.

First-half strikes from Pogrebnyak and Konstantin Zyrianov put Zenit firmly in control following a 1-1 draw in the first leg in Munich last week.

Viktor Fayzulin added a third shortly after the interval before Pogrebnyak sealed a memorable win with his second of the night in the 73rd minute.

Bayern, who won the UEFA Cup in 1996, had the lion's share of possession in the first half but rarely troubled Zenit keeper Vyacheslav Malafeev.

Zenit will be looking to emulate fellow Russians CSKA Moscow, who won the trophy in 2005.
