Citing a poor spell at Bayern Munich, the 67-year-old believes that the Germany man would be better off if he stayed at the RheinEnergieStadion despite interest in the playerLukas Podolski would be better served by staying at Koln, despite interest from abroad.
The 26-year-old has been touted as the man to solve both Arsenal and AC Milan's striking problems, but Netzer believes he is not cut-out to play for a top European club, citing the 26-year-old's unhappy three-year spell at Bayern Munich.
"He is no player for a great European club," Netzer told Bild. "Even during his time at Bayern Munich he was missing clout and assertion.
"For Podolski it would be ideal if Koln would increase their contract offer - that would provide him with better opportunities."
Podolski has 18 months remaining on his contract, and Netzer went on to state that should be leave the RheinEnergieStadion, he should stay in the areas surrounding Koln.
"An alternative would would be a big club in the vicinity of his home in Koln, so he could combine business with pleasure."
Podolski scored 14 goals in his sixteen Bundesliga games in the first half of the season.
