Liverpool, Manchester United and Tottenham have checked on Augsburg left back Philipp Max.
The 24-year-old won a silver medal as part of Germany's 2016 Olympic squad and has been impressing scouts with his high level performances in the Bundesliga this season.
Max has been touted for a place in Germany's World Cup squad owing to his consistency and increasing number of assists as Augsburg make their best start to a Bundesliga season.
He can play in a more advanced role too.
Everton have also sent scouts to watch Max as Premier League sides consider their options for what is becoming a well sought-after position.
United and Chelsea have both shown interest in the likes of Alex Sandro at Juventus and Porto's Alex Telles, who Tottenham have also watched.
Max extended his contract this year until 2022 and his value is escalating with increasing interest.
