Bayer Leverkusen went second in the Bundesliga table on Sunday with a 4-2 win at home to strugglers VfB Stuttgart that dropped their guests further into the relegation battle.
Stuttgart put up a real fight as they came from behind twice and refused to yield until Leverkusen's Stefan Reinartz headed the winning goal on 81 minutes before Stefan Kiessling netted his second of the game in added time.
The win leaves Leverkusen 10 points behind leaders Borussia Dortmund and knocks defending champions Bayern Munich down to third in the table.
The hosts opened the scoring when Germany forward Kiessling drilled home a left-footed shot after just six minutes, only for Stuttgart's striker Martin Harnik to equalise ten minutes later.
Leverkusen midfielder Gonzalo Castro put his side ahead again on 41 minutes, but Serbian midfielder Zdravko Kuzmanovic levelled again for Stuttgart mid-way through the second half.
Defender Reinartz then sealed Leverkusen's victory with a header nine minutes from full-time before Kiessling scored his second in the first minute of injury time.
