'He hasn't proven anything': Van der Vaart challenges Antony to emulate Rashford
Van der Vaart has been critical of Antony already this season, and the former Netherlands international has claimed that the winger needs to prove himself at United.
"Do you know what it is with Antony... He is of course a great talent and a great player, but he shouldn't believe in himself very much," Van der Vaart told Ziggo Sport. "He's just a good player, who hasn't proven anything yet."
He added: "I do like a show, but only when I can. Of course you have to have that feeling. He has played some good Champions League games, he's come in reasonably well with the Brazil national team a few times, he's made a big move and hasn't done much at Manchester United yet."
"He shouldn't think: 'I've made it and I'm going to show it to the whole world by doing crazy things'. No, he has to decide games, like Marcus Rashford is doing now. Then you can do something crazy for once. But he has to be very humble, try really hard and shoot or pass those balls in."
