The goal-scoring prowess of FC Bayern München striker Robert Lewandowski has not gone unnoticed by TSG 1899 Hoffenheim defender Fabian Schär.

The Switzerland international will lock horns with the indomitable Pole at the Allianz Arena on Sunday afternoon in a re-run of one of his sternest tests to date as a professional footballer.

'They're a top side'

"Lewandowski is an unbelievable striker who has everything, so we'll all have to rise to new levels to compete with Bayern," Schär told club website www.achtzehn99.de. "It would be wrong to concentrate on just him, though. We know exactly how good the Bayern players. Even when they're vulnerable, they're a top side."

Schär witnessed Bayern's qualities first-hand back on Matchday 2. Despite falling behind to Kevin Volland's ninth-second opener and having defensive lynchpin Jerome Boateng sent off following Thomas Müller's equaliser, the 24-time Bundesliga champions went on to win the game thanks to none other than Lewandowski.

'We've got nothing to lose'

A repeat result this weekend could send 17th-placed Hoffenheim back to the bottom of the standings, but they at least travel to Munich buoyed by a notable 1-1 draw with top-four candidates Bayer 04 Leverkusen last time out. "It was a good performance and gives us something to work on for the rest of the season," 24-year-old Schär opined.

Indeed, in preventing Leverkusen's Javier 'Chicharito' Hernandez from adding to his 11-goal debut Bundesliga season haul, the former FC Basel 1893 man succeeded where so many others before him have failed. If he can do a similar number on the 17-goal Lewandowski, Schär will be a fraction of the way to helping Die Kraichgauer achieve their Matchday 19 objective: "We want to take something from the game."
