Arsenal youngster Serge Gnabry will spend the 2015-16 season on loan at West Brom.
Gnabry broke into the first-team picture at the Emirates Stadium during the 2013-14 campaign, but saw his progress stutter due to injuries last season.
The 20-year-old becomes Tony Pulis’ fourth signing of the close-season.
“I’m very delighted by the move,” Gnabry told West Brom’s official website. “I see the opportunity that I can play, it’s a good club and I’ve heard good things.
“I’m very happy that I’ve signed here. I’ve got good impressions and I feel it’s a good environment for me to play and also develop as a player.”
Arsenal boss Arsene Wenger expects Gnabry to thrive under Tony Pulis’ guidance, and says the loan spell will be key in the young German’s development.
He said: “We know Serge is ready to play in the Premier League, but we know as well that what is needed for him is to get 25 to 30 games to show that he can produce it on a regular basis and cope with it physically.”
