Indeed, there is no doubt about Lukaku's quality with As Roma, last season he was able to play well and was always the main starter in the As Roma squad, but we also have to look at his physique as he gets older, whether Lukaku will be able to compete with the young players at Napoli and Conte was able to bring him to Napoli. Honestly, I doubt Lukaku's quality with him being 31 years old now, with so many young players and even big clubs competing to use young players from their academies or looking outside the league, of course this is a decision that requires There is a risk for Conte in selecting attacking players, because in this era it is really difficult to find good players and most of the players are expensive but will not necessarily meet the club's expectations.
Lukaku's performance has really declined and it's been clear in the last few seasons but Antonio Conte quite likes players with Lukaku's characteristics, that might be the reason and I think if a player fits the coach's scheme given then it's not impossible that he can rise again
And another reason I think Conte is interested in Lukaku is because it is realistic to recruit him because his price is cheap, it is quite reasonable for the Napoli club because it is unlikely that they will be able to spend a lot of money on a striker so the coach is interested in signing Lukaku.
Now Lukaku is no longer needed at Chelsea, so it is very likely that the Chelsea team will release him at a cheap price, even though the price is a little expensive now, but I think it can still be negotiated.
I think right now Conte is trying to make a big mistake by considering to get Lukaku back to his team even at his current performance right now, Lukaku may not be expensive right now because of his age and the level he is right now but Conte considering to bring him back to the team means he is not ready to win trophies with the team next season.
I don't think Chelsea is ready to keep Lukaku in the team so they have no other options other than to reduce his price so Conte can bring him to his team. Chelsea can not keep him because he is no longer sharp in front of goals and for a team like Chelsea that has been struggling in the last two seasons, so they will definitely not want Lukaku back to the team since he's not getting younger anymore.
