Former Germany manager Berti Vogts hopes Lukas Podolski's summer move to Arsenal will allow the striker to improve his attitude and application after leaving Cologne.
Podolski rejoined Cologne from Bayern Munich in 2009 and, despite scoring 18 goals last season, was unable to prevent the club from dropping out of the Budesliga.
During his three years RheinEnergieStadion, Podolski gained a reputation as somewhat of a playboy and his efforts on the training field were questioned by some.
Vogts has been particularly critical of the 27-year-old for his behaviour in the past and believes Podolski is better off out of the city where he originally forged his reputation.
The former Scotland manager now believes a move to Arsenal will encourage the best out of Podolski, who has already impressed since his move to the Emirates Stadium.
“I am happy that Podolski has left Cologne. He had too many friends in the city," Vogts said, according to The Sun.
“He got praised as a great runner if he ever got back to defend three times in a game. He got an easy ride and he believed his own publicity.
"But now he has a coach at Arsenal in Arsene Wenger who will make him work hard in training as well as matches.
“If Podolski fails to train properly twice or three times he won’t get games. That is the way to develop him into a true professional.”
Podolski has scored three goals in six appearances since becoming a Gunner and has been tasked with compensating for the loss of Arsenal captain Robin van Persie.
