Angha's current deal with Arsenal expires this summer, and he is reported to have agreed a four-year contract with Nurnberg pending the outcome of a medical.
Nurnberg have not commented on whether a deal has been reached, but general manager Martin Bader acknowledged Angha is on their radar.
"Martin Angha is a player we are strongly interested in," said Bader.
Angha has made two appearances for the Arsenal first team this season, with his only start coming in the 6-1 demolition of Coventry City in the Capital One Cup.
The 19-year-old joined the Gunners from Zurich in 2010, and although featuring regularly for the Academy and reserve sides he has not made strong claims for a place in Arsene Wenger's side.
