Manchester United and Arsenal are monitoring highly rated Hertha Berlin youngster Arne Maier ahead of a race to sign the Germany Under-21 international in January.
Rumours first surfaced in September that Premier League clubs were considering a move for the 19-year-old, and with the January transfer window looming, there is renewed interest.
Maier is likened to World Cup-winning German midfielder Toni Kroos, and with over 30 international caps at youth level, he will hope to join Kroos in Joachim Low's senior squad next year.
A midfielder by trade, Maier broke into the Hertha team last season, becoming a regular starter in Pál Dárdai's side before injury ended his campaign early.
He has quickly established himself as one of the first names on Dárdai's team sheet and is yet to miss a minute of league football this season after 14 rounds of Bundesliga action.
On receiving comparisons with Kroos, Maier told the Berliner Zeitung recently: "It's nice to hear something like that. But football is a team sport. In addition, there are no guarantees that all this will happen. You have to work hard every day.
"My game is characterised by calmness on the ball and awareness. I try to control the game and get on the ball as often as possible."
Hertha are sixth in the league table after beating Eintracht Frankfurt on Saturday, just four points behind Bayern Munich, but there is a feeling that Maier is destined for greater things.
Arsenal already have a strong trio of defensive midfielders, with Matteo Guendouzi providing backup to the regular starting pair of Granit Xhaka and Lucas Torreira, but Emery may pursue Maier if he is seeking further strength in depth.
Scouts from both clubs are expected to be in attendance when Hertha face Stuttgart next Saturday.
