Lukaku, 22, scored both goals as Everton beat his former club Chelsea 2-0 in the FA Cup on Saturday evening, with his first goal a quite sensational goal.
Picking the ball up on the left hand side, Lukaku drove into the Chelsea area, beating Cesar Azpilicueta, Branislav Ivanovic, John Obi Mikel and Gary Cahill before slotting past Thibaut Courtois for a quite brilliant individual strike from the Belgian international.
Lukaku has now taken his tally for the season to a whopping 21 goals, cementing himself as one of the most dangerous and lethal strikers in the Premier League.
Even with that reputation, the way the giant Lukaku slalomed his way through the Chelsea defence surprised some, and pundit Garth Crooks was one such viewer left startled by Lukaku's run.
Crooks told BBC Sport that he was surprised by Lukaku's goal because he didn't think Lukaku was capable of such skill, before making two bold claims about the striker.
Crooks added that he felt it was not only Lukaku's best ever finish during his career, but also his best performance since signing for Everton back in 2013, initially on loan before making that move permanent in 2014.
"What a performance by Romelu Lukaku against his old team," said Crooks. "I didn't think that Lukaku was capable of scoring his first goal which was, without doubt, the best finish I have ever seen him produce in arguably his best performance in an Everton shirt," he added.
