Nuno was speaking ahead of tomorrow's clash against Aston Villa at the City Ground.
"He is at his peak - and I hope it continues. He is in his best moment,” Nuno said.
“There is no age (limit), everything is possible. It is something we should all reflect on, especially now.
“Squads are getting younger and younger again, because we tend to always look for the next prospect and the next thing. Sometimes you don’t realise that a 33-year-old player can perform as good and be the best.
"The knowledge he has acquired through his career reflects on the pitch.”
