You are right, Inter is the most serious team to bring Lukaku they make every effort to get this player we don't know what the reason but maybe because Inter has no other choice and Lukaku is considered cheap and can be relied on. The rumors are Inter ready to release 6 players in order to secure Lukaku so we can imagine how important Lukaku for Inter even though the performance wasn't very good last season.
It's high time Romelu gets a solid future at Chelsea or he looks for a possible exits from the club. Romelu Lukaku has been an essential player for Inter Milan since his arrival, and the club is always willing to go the extra mile to keep the Belgium international. Meanwhile, Chelsea needs him to represent them at Stamford Bridge, and they are ready to support him. Inter Milan are pressing for another loan term for Lukaku, which Chelsea is willing to turn down because they have enough loan contracts for Lukaku and want him to work under the new manager, Pochettino.
