Arsenal are concerned about losing Chris Willock this summer.
The Daily Mail says Willock, 19, is viewed as one of the brightest talents at the Emirates Stadium and has already made his first-team debut appearing twice for the club in the EFL Cup earlier this season.
But the forward is in the final three months of his existing deal and the Gunners are yet to agree an extension.
The club have initiated contract discussions but the landscape regarding Willock's future has changed in recent weeks with a number of clubs registering an interest in the youngster.
Everton, Southampton and Bournemouth are among the Premier League clubs who want to take Willock, while Borussia Dortmund are also monitoring the situation closely.
