It is very close and also some reports say that Ronaldo has asked Juventus to let him leave but he won't be leaving for free as he is in contract and maybe City thinks 30m is too much for 36 year old maybe. Right now according to oddschecker.com, Ronaldo to City is at as low as 1/5 and that goes to say how close it is. Still things could change at any point and it is not good to actually rely on bookmakers odds to see but they make the odds after pulling out information from multiple sources-they could be right or could be wrong.
