One of the most thrilling Bundesliga title races in years was thrown wide open again as Mario Gomez hit four goals to inspire VfB Stuttgart to a 4-1 victory over leaders VfL Wolfsburg.

Wolfsburg were joined at the top by champions Bayern Munich who won 3-1 at Energie Cottbus.
With all the teams in action again on Tuesday and Wednesday, Wolfsburg lead on goal difference from Bayern on 60 points with three matches left.
Hertha Berlin are a point behind after beating VfL Bochum 2-0 while fourth-placed Stuttgart complete the title log-jam on 58.
Winter champions Hoffenheim are 12 points off the pace after their dream first season in the top flight stuttered after Christmas.
Stuttgart stunned the visitors with a goal in the first minute on Saturday when the unmarked Gomez nodded in from 11 metres.
The Germany striker, who has not scored for his country since March 2008, added his second from close range in the 20th with Wolfsburg's defence in disarray.
The leaders hit back before the break with Edin Dzeko netting his 20th goal of the season.
Any thoughts of a comeback were short-lived when Gomez fired home from 14 metres on 63 minutes before putting the seal on his spectacular performance with another header after 77, his 23rd goal of the season.
"We imagined this match a bit differently," Wolfsburg coach Felix Magath said.
Wolfsburg have lost two of their last three matches after winning 10 successive games.
Bayern, with Frenchman Franck Ribery on the bench, were the more aggressive side at Cottbus and striker Lukas Podolski had a powerful early shot brilliantly saved by keeper Gerhard Tremmel.
Hamit Altintop also went wide with a close-range effort before Bayern struck on 23 minutes thanks to Argentine Jose Sosa's eight-metre volley.
The visitors twice went close when Mark van Bommel's header was cleared off the line and Altintop was thwarted from the rebound.
Lowly Cottbus levelled a minute before the break through Ivica Iliev but defender Martin Demichelis restored Bayern's lead in the 62nd and Podolski made sure of all three points with a low shot four minutes later.
Ribery, who came on as a substitute in the second half, had a 90th-minute penalty saved by Tremmel.
"If you look at the table you will see how important this win was," said interim Bayern coach Jupp Heynckes who has two victories in two matches since taking over from the sacked Juergen Klinsmann last month.
"There are four or five teams crammed together at the top.
"Our aim is direct Champions League qualification and it is now possible again."
Borussia Dortmund hammered bottom team Karlsruhe 4-0 to move to fifth.
Sixth-placed Hamburg SV, also on 55 points, visit Werder Bremen on Sunday.
