"In terms of diving Luis needed to be told and he got his act into gear last season with that.
"That was before the Ivanovic incident, anyway.
"The same goes for the likes of Ashley Young too, who's been involved with diving, or simulation as it's called.
"It's down to managers to tell them what's right and what's wrong."
