Arnold, who has progressed through the ranks at the Championship side, signed a new deal with the Royals earlier today.
“I’m excited to be working with him, having watched him play a number of times for Reading U21s last season,” Gareth Ainsworth told wwfc.com.
“I feel he’s got something. He can play anywhere on the right, is energetic and has pace and strength.
“Hopefully he can follow in the footsteps of the successful loan signings we had last year.”
The 19-year-old becomes Gareth Ainsworth’s second signing of the summer after recruiting goalkeeper Charlie Horlock.
