Borussia Dortmund are interested in making a move for Tottenham Hotspur midfielder Lewis Holtby, [football] direct news understands. The 23-year-old midfielder left Germany last summer for Spurs in 2013 but despite a successful debut season, he was deemed surplus to requirements and loaned out to Fulham. Signed by former boss Rene Meulensteen, Holtby immediately made an impact and has thrived under new boss Felix Magath, playing a vital part in their win over Newcastle earlier this month. Those types of performances have seen the youngster gain plaudits from other Premier League clubs, including Everton. However, [FDN] understands that a number of German clubs, notably Borussia Dortmund are leading the race to make a summer move. Holtby would seemingly enjoy a move back to his native Germany over a stay in England.
