It must be hastened for AS Roma to bring in Lukaku as soon as possible, because Juventus also has the same interest as the Belgian Bomber, due to the stricken crisis, so many injured players have made AS Roma need the figure of Lukaku to sharpen AS Roma's attack power, if not sooner then AS Roma will lose that opportunity to have Lukaku.
And indeed at this time there are very strong rumors that Jose Mourinho is interested in bringing in Lukaku after the Belgian national player is no longer used by Chlesea, but that is with a loan option.
I think if this offer is seriously made by the Roma team then it will most likely be realized after Chelsea really don't want Lukaku anymore.
Lukaku will prioritize to play in Serie A than in other leagues as he does not fit with Premier League. Ligue 1 and Bundesliga are not his favorite leagues and La Liga likely does not fit with Lukaku style too.
In Italy, he betrayed Inter Milan and Juventus already stopped their interest on him. So the offer from Roma will be interesting for Lukaku as it is one of his best chances to leave Chelsea this summer. The barrier is his high salary and if Chelsea agrees to share it with Roma, the loan transfer will be executed. As with finance of Roma, they will surely not be ready to pay 100% salary of Lukaku.
It's a shame that a player such a Lukaku is still looking for a club to join this summer, a player that would had been the current frontman for Intermilan and would had probably played I'm the champions league again this season but his betrayal to them have left him stranded at Chelsea because they don't have any interest in featuring him this season, now the only option he has is to hope that an European club comes for his demands.
I don't feel pity for him because he betrayed a club that made him popular against and even helped bring out the best in him again after some poor stats at Chelsea too bad the deal with Roma is not a permanent one if it finally comes through, which means he'll still returns to Chelsea after the end of another loan spell, but that won't be an issue for lukaku do far he'll move to club where he'll get playing time abd away from warming Chelsea's bench.
