I think only Pintus would not be enough. Conte was also instrumental. Because when I look at the shape Hazard is in, I don't think the Pintus cure is doing the same magic as it did for Lukaku back in 2019/2020. Besides I don't think with strikers like Osimhen, Haaland (I'd even add Vlahovic) around, they would be looking for a now ex-player like Lukaku. The guy has less league goals than Junior Messias.
Also he is just simply two years older and it's been 2 years since he's shown any decent form. This year Lukaku hasn't been able to even produce one sprint or beat any opponent with his speed. Zero. Even Lautaro who's never been the fastest is able to outspeed defenders or at least use his physique once he's ahead of them.
Even physically other t han leaning on the defender and kick the ball back when his teammates passes it to him, you can see that there is not much left from the Lukaku who was seen physically battling against Koulibaly. After 30 minutes he looks absolutely exhausted, even right when he first steps on the pitch he is sweating like he's been playing fof 70 minutes.
