Arsenal midfielder Chris Willock could be lost to English football this summer.

Off contract at the end of the month, Willock has so far failed to agree new terms with the Gunners.

Manchester City and Celtic have been linked with the 19 year-old England youth international, but are not alone.

German giants Borussia Dortmund are also interested in Willock, having become aware of his potential in action for the UEFA Youth League.

Dortmund can snap up Willock for a minimal compensation fee from July 1.
