Arsenal teenager Eddie Nketiah has signed a new "long-term" deal at the club.

The 18-year-old announced himself to supporters when he scored two goals after coming off the bench to rescue Arsenal a 2-1 win in their Carabao Cup tie against Norwich in October.

Nketiah is one of three Arsenal youngsters to have committed their futures to the club on Wednesday, with Matt Macey and Ben Sheaf also signing new contracts.

"Delighted to have signed a new long-term deal with Arsenal, looking forward to pushing on and continuing my development at this great club," Nketiah posted on Twitter.

"Thanks to my family and friends for all the support, God is good!"

Macey and Sheaf also made their first-team debuts this season, featuring in Europa League and Carabao Cup games.

A club statement said: "We would like to congratulate all players on their new contracts and wish them every success as they continue their development with the club."
