With the 28-year-old heading towards the final 12 months of his current contract and no extension talks planned until the summer, uncertainty continues to shroud his future at Emirates Stadium.
Several leading sides from across Europe have been mooted as potential landing spots for the South American, with Bayern the latest to head that particular queue.
Former Germany international Lehmann believes Sanchez would be a solid addition for the Bundesliga champions, although he acknowledges that they are already well-stocked in wide areas with Arjen Robben and Franck Ribery on the books.
“He would fit in at Bayern, although he is not the typical wide player they are seeking," the ex-Arsenal goalkeeper told Sky Deutschland.
"He likes to cut inside, I have seen players that make better decisions on the pitch, but perhaps he can learn that.
"He is a street footballer, you notice that when he is on the pitch.
“Playing him in a system is not so easy but it would be nice to see him in the Bundesliga."
Sanchez has netted 24 times for Arsenal in all competitions this season, with Arsene Wenger opting to use him as more of a central striker this season than a supporting forward in a wide berth.
