Ferdinand heaped praise on leading Premier League scorer Kane, with the former United centre-back particularly pleased with the 24-year-old's link-up play. "I think Kane showed today why he's the best striker in the league and one of the most potent in Europe because he's bullied United's centre halves," Ferdinand told BT Sport. "He totally dominated them physically and brought other people into play. The contrast between him and Lukaku today was so evident it was unbelievable from up here where we watched it. "The ball going into him, sticking, holding centre halves off and bringing others into the game. That's a real No. 9. That's what you want to see a No. 9 do." Kane tops the Premier League charts with 21 goals, 10 more than United's Lukaku. Former Spurs boss Harry Redknapp added: "There's no comparison. He's on a different level to Lukaku." Source: Goal.com Lukaku, is sporadic but I try to give him the benefit of the doubt as he is in his first season at the club. Sometimes he scores really good goals, creates for others etc. But majority of the time I'm let down by his holdup play, he is a big big guy but doesn't seem to use his strength often enough. He is a brickhouse, but can't really shield the ball or he is never on his toes when reacting to a through ball. Lastly, he need to work on winning more headers from De Gea Goal kicks etc. If he is to be our main number 9 for the next few seasons he needs to improve as currently he is just not good enough overall. Your thoughts on Rio's, Harry's and my words???
