Today, in the Championship Play-Off Final against Crystal Palace, Almunia can lead the Hornets back into the Premier League to set up an emotional return next season to The Emirates.
"It is a bit weird," said the 36-year-old. "There are only 50 metres between the two fences.
"Some days I shout over because I can hear the goalkeeping coaches Gerry Peyton and Tony Roberts.
"One day Gerry shouted back, 'Manu come over here and train with us'.
"I message quite a few players but my close friend was Robin van Persie. But there are still nice people there.
"The best relationship I keep is with some of the staff, like the kitman Vic Akers and his son Paul."
