The Stoke midfielder was heavily criticised for a tackle on Tottenham's Paulinho last month that is likely to rule the Brazilian out for a month.
He said: "There's no point in me speaking about it, it's done and dusted and we move on.
"That's what happens in football, opinions, but you have to react in the right way and we've done that with a win and we're happy.
"I don't need to answer any questions. For me it's about winning games and scoring goals. If I keep doing that, I'm playing well and the team are winning, then that's the important thing."
