What you say I think is not true, Lukaku's performance has really declined now just look at the last few seasons, Chelsea doesn't want him anymore and at Roma last season he couldn't contribute much and even at the Euros in Belgium Lukaku didn't do anything that he could. help his country, this player is no longer as sharp as before, his performance has dropped drastically.
There are still many other options for Chelsea if they are still too determined to buy better players, because Chelsea will not lose enough if they fail to get Lukaku in the transfer market this season. Now is the time for every team to find young, talented players for their squad before the season starts, because players who are less sharp no longer seem to be an option to look at at this time, especially for teams who are trying to improve their performance next season.
