What Milan is thinking is very far from the fans' expectations and if it is true that Milan makes an offer to sign Lukaku this is definitely a setback. We know Milan have just secured around 70 million euros fresh funds after successfully selling Sandro Tonali to Newcastle and I think Milan should be able to find a much better striker than Lukaku with these funds. At Inter Lukaku has often failed to prove his worth and even though Milan started their bid at 40 million euros I don't think it was worth it and it would be better for Milan to start discussing his options again.
Lukaku's performance in intermilan was not so bad as you said. Even though lukaku has failed to bring intermilan to win UCL but his performance was quite well last season. Intermilan was winning a trophy + it has gone to the final of UCL which was a great achievement by intermilan. The only problem if lukaku never had interest to join in ac milan. Acmilan was making the wrong decision to tageting him as a new striker for the club.
I think that ac milan shall not try to take lukaku. Ac milan must have found another player that can become a new striker for ac milan upcoming season. Lukaku will never ever fit for the club. He is only wanna playing for intermilan.
Even he rejects to play for chelsea and he was only going for intermilan. Chelsea even ac milan must retain themselves in using this guy as striker.
Indeed, Lukaku is not entirely bad, but when a team like Milan, who are also less consistent every season, that can be something that will make them difficult in the end. It must be admitted that Lukaku is overly confident, he always feels needed for other teams and he is not aware that his performance continues to decline every year. I think Milan need to be wiser in using the available funds to get quality players and to achieve this they have to find a striker who can be a mainstay when the team is struggling to score goals. Milan is one of the big teams in Serie and this decision must be carefully thought out if they are interested in signing Lukaku.
