David Watson was with CH at both Birmingham and Norwich as GK coach but wouldnt think it will be him as he joined Southampton at the start of 14/15 season.as GK under Koeman.
What is the odds on Paul Barron becoming GK Coach. He was at Peterborough and joined Newcastle when CH was manager and left when CH did. He is not with a club now, so an option for somebody who is known to CH.
