Stoke winger Etherington: I haven't been good enough this season
Etherington admitted he was not pulling his weight.
The winger said: "I will be the first to admit my form has not been as good as the last two seasons.
"I have had some indifferent performances, where I haven't done myself justice, and I have had some good performances.
"But hopefully now, with some big games coming up, I can step up to the mark and put in some big displays."
