Arsenal face battle to keep hold of Sam Greenwood.

The Sun says the striker is being watched by Bundesliga clubs.

At the Emirates he is seen as a modern-day forward who could make the first team after getting plucked from Sunderland last summer.

The 17-year-old had spent a decade at the Stadium of Light but made the big move south and has already won silverware at his new club - putting him firmly in the sights of Unai Emery.

"Leaving my town, friends and family was quite daunting, it felt like a big task, but I was keen to push myself and now that I'm here I feel fully settled," he told Arsenal.com.
