Watkins responded to his omission in the best possible way on Sunday afternoon, scoring in Villa's 2-0 win over West Ham as Unai Emery's side strengthened their hold on fourth place in the race for Champions League qualification.
Speaking after the game, Watkins admitted he had feared he would be left out but reiterated his self confidence and pointed to his positive overall record with England.
He revealed: "Everyone wants to play for their country but I expected that because my form has not been that great.
"I know what I can do and when I put on an England shirt I feel like I have always performed well."
