FOLLOWING Borussia Dortmund's announcement that Ilkay Gundogan will not be renewing his contract at the club, Starsport profile the Manchester United and Arsenal target.
Gundogan was born on 24 October 1990 and is 24 years old.
He plays in central midfield.
He is valued at £20m and his current contract at Dortmund expires in June 2016.
He began his professional career at Vfl Bochum before moving to FC Nurnberg in 2009 as an 18-year-old.
Dortmund signed him for around £4m in 2011 after helping Nurnberg finish sixth in the Bundesliga as a replacement for Nuri Sahin who had departed for Real Madrid.
In his first season with Jurgen Klopp's side he helped them secure a first domestic double of the Bundesliga and German Cup.
Gundogan was a key part of the Dortmund side which progressed to the Champions League final. He scored Dortmund's goal from the penalty spot as they lost 2-1 to Bayern Munich in the final at Wembley.
He has since struggled with injuries, making only one appearance last season and 28 during this campaign. He missed the 2014 World Cup through injury.
He suffers from spondylolisthesis - a deformity in the lower back - which can lead to hamstring injuries. The back injury he suffered in August 2013 kept him out for over a year.
He has won nine caps for Germany and scored two goals. He has also represented his country at Under-18, Under-19, Under-20 and Under-21 level.
