Werder Bremen star Marko Marin is being watched by Tottenham.
The Observer says Spurs boss Harry Redknapp likes Marin, the 22-year-old Werder Bremen and Germany left-winger.
"You've got to add to the squad," Redknapp said.
"The chairman knows if we can't move on, then you have to accept trying to get into the Europa League every year and trying to finish sixth or seventh. But if you want to try to make the Champions League, you have to keep improving."
