However, Manchester United legend Rio Ferdinand believes the Dutchman has the perfect chance to showcase his true caliber when the Reds take on Manchester City on October 16 in the Premier League.Coming up against an in-form Erling Haaland, Van Dijk can reaffirm the Kop of his quality with a statement performance. Speaking on BT Sport, Ferdinand said (via The Mirror):“It's a great opportunity. I used to look at these games if we were a bit out of form and going into a big game you should look at it as this is the perfect game. This is what Liverpool should be thinking."The former defender further added:“This is Virgil van Dijk's time to go and shut a few people up. People are questioning him now; he was almost invincible at one point, the best player on planet earth right now, the most in-form right now, Haaland is coming to town, 'I'm going to put it on him, shut it up.' All of a sudden, the dynamic changes and the confidence grows, and everyone is back on the path.”Following a slow start to the season, Liverpool are currently languishing in 10th spot in the table with 10 points in eight games.
