Liverpool legend Jamie Carragher has urged Everton winger Anthony Gordon to cut his diving.
Gordon, who caused Liverpool trouble throughout Sunday's derby, was booked in the first half after going down over an outstretched leg from Liverpool midfielder Naby Keita. He was adjudged to have dived.
Commentating on the game for Sky Sports, former Liverpool man Carragher said it was something he had noticed in the young player's game and encouraged him to "keep an eye on it".
He said: "Anthony Gordon has been a revelation since Frank Lampard came in. He just jumps over Naby Keita's outstretched leg.
"There's been a tendency of this from Anthony Gordon, in the few games we've seen him.
"He's frustrated, he can't believe it... but that's crept into his game. He's somebody we've got to keep an eye on now.
"I don't think it was a penalty, the referee was in a great position."
