They knew it would had been tough to get another club that would get and the player might not really want to move to the Saudi league, so they finally decided to bargain with Roma and instead of keeping him in the team for another season and paying him huge wages without a playing time cause Pochettino does not have any plans to use him in his team, I was really surprised that a deal between Juve and Chelsea collapse because they were seriously interested in Lukaku and a deal looked likely but it's a good thing he finally left to a league he's has an experience in and has performed well in, Lukaku would make a fine support to belloti and would make a fine support for belloti and also their frontline looks stronger,if he had remained in Chelsea it would has been bad for his career staying on the bench without playing time.
