"I was sad to see Brian McDermott leave Reading," Keown wrote in his column in the Daily Mail.
"He has done a magnificent job for 14 years in various roles and he always impressed me when I watched him at close quarters.
"He loved his players and they loved him — which is rare when you are near the bottom of the table. I hope he gets back into football very soon."
Reading are currently 19th in the Premier League.
