The Magpies took an early lead in the Premier League game against Manchester City, but they conceded five goals thereafter and went down 6-1.
Former Newcastle star Watson was following the match, and he was stunned to see Steve McClaren’s side suffer a spectacular collapse.
The Geordie is concerned that there were no British players in Newcastle’s starting lineup against City.
Watson has also named three British players Newcastle should have tried to sign in the summer transfer window: Blackburn Rovers striker Jordan Rhodes, Queens Park Rangers forward Charlie Austin and Burnley midfielder Scott Arfield.
