Christino Ronaldo will definitely be a boost to the current strikers we have at Chelsea and with the likes of Hakim Ziyech playing as brilliantly as he is at the world cup, if he get more playing time at Chelsea then he'll definitely keep up that performance and energy meaning, we got our right wings settled as Reece James will also be returning from injury. With both Reece James and Hakim ziyech playing we can get good crosses for header and who would you want most at the end of those crosses than Ronaldo. The media can say all the bad things about this guy (Ronaldo) but the fact reminds he's one of the greatest to have ever played football.
I think signing Ronaldo will totally depends on the managers approval because it will be ugly if we get similar situation that happened between Manchester united coach (Ten Hang) and Christino Ronaldo to repeat itself at Chelsea. Graham Potter has to be sure he can manage Ronaldo and the media very well before agreeing to signed the player. This move will also be beneficial to Chelsea financially considering the media is all over Ronaldo and this will increase more publicity for the club and merchandise sales.
Having Cristiano Ronaldo at Chelsea will make sense, they're short in the attacking options if they can get him before the game against Borrussia Dortmund, then I can say they have a chance to win Dortmund.
It's pretty sad he's leaving so early in the world cup, ad they lost to Morocco today as he was spotted shedding tear's, what a painful exit for his last world cup game.
The Coach has a role to play though in his arrival, but since the owner wants him in the club, I think it will be smoothly done. The news of him moving to Saudi Arabian side has also been on air, I don't want him really to relocate to that league.
