Romelu Lukaku has been labelled "dull" and "functional" by former Italy striker, Paulo Di Canio, who blasted the Belgium international's performances at Chelsea.
Lukaku returned to Stamford Bridge earlier this summer in a £98m deal from Inter, but following a strong start back to life in the Premier League, his goals have dried up, significantly.
The 28-year-old was signed by the Blues to help them fix their striker issues, but Di Canio believes Lukaku is merely a "dull" and "functional" forward.
"I heard (Giuseppe) Bergomi comparing (Napoli striker Victor) Osimhen and Lukaku. But Osimhen has a different spirit, he's not dull like him," the former West Ham and Sheffield Wednesday striker said on the Sky Calcio Club show, via the Daily Mail.
'When the difficulty increased he scored no goals in five games with Chelsea. And it's not Chelsea's fault, they are first (in the table) even without his goals. Even if Lukaku is stronger than Llorente. Lukaku is functional to a certain type of game."
But Thomas Tuchel came to his star's rescue, explaining why his goals have dried up of late. 'I felt him a bit tired. Altogether we produced a very strong 60 to 75 minutes, including Romelu and Timo (Werner)," the German claimed after Chelsea's narrow win at Brentford.
"Both of them, Romelu and Timo, were too far away to help us escape the pressure. That was the problem, but I have no concerns. Normally the best thing is that he scores but he is very unselfish at the moment, looking for Timo in good situations."
