Lukaku will face Tottenham Hotspur on Sunday and Arsenal legend Keown has explained how to prevent the striker from continuing his hot streak, having scored four goals in his first four Chelsea games
Having been brought in as the perceived final piece of Thomas Tuchel’s puzzle during the summer transfer window, the £97.5 million man is doing a good job of paying back the Blues’ investment.
The striker has four goals in four games since re-signing for the club who sold him in 2014, failing to net in all but one of those.
Lukaku is now looking to lead Chelsea to the Premier League title and bagged a header in Tuesday’s Champions League group stage victory over Zenit St. Petersburg.
But the Belgian can be stopped according to Keown, who won three Premier Leagues with the Gunners.
He told talkSPORT : “When you’re playing against him, every single ball is a contest.
“I don’t want him to hold on to me to feel me, I wouldn’t want to get too tight but I’m going to hit him. Come two or three yards back, and when I hit him, I’m going to hit him with everything.
“I’m going to be in his ear as well, I’ve got to tell him he’s rubbish, it’s all hype, you’re playing against me today, you’re not going to get that kind of space.
Keown added: “You can’t let him build into the game and then when it comes, you’re going to [need] to have the game of the season by the way, physically you’re going to have to be up for it.
“He is fantastic in the air, we see the goal he scored in midweek, he’s got everything to his game and he is super confident so you’ve got to make him feel this is different today.
“I’m a little bit different to the rest and I am going to make it tough for you.”
Lukaku will face off against Tottenham’s Harry Kane at the weekend, who is a “very different” kind of striker in Tuchel’s opinion.
“I find that Romelu plays a bit higher up the pitch while Harry likes to drop into No.10 positions, into pockets and turn to assist,” the German tactician explained.
“He has a super partnership with Son so he is very strong in finding space between the lines. Romelu likes to get up higher in the pitch.
“But they also have similarities. They love to score and they score whenever they play, they are up for it and it is a certain mindset that you cannot learn.”
Tuchel continued: “I am pretty sure they both started showing this mindset when they started playing football when they were five, six, seven years old. These guys are born to score goals and if they do not score they are not happy.
“They have a different style. Romelu is more physical. Harry is for me between the lines and open space.
“Both are super dangerous and key players. In the end it is a fascinating dual for both No.9s but it stays a team effort.
“If you want to win matches like this you need to be strong as a team. Maybe this is also a similarity. I feel both of them are team players.
“Harry does everything for his team whether he plays for Tottenham or England, he is not shy to work defensively. He does what is needed to do, to defend set pieces and whatever.
The Blues boss affirmed: “Romelu is the same, he is here to help us win titles. That is what big players do.”
