Linares is not even that big

[M Bison]

The difference in size was noticeable, Linares having the larger frame / shoulder width / wingspan. I can't see Lomachenko ever being a force at 140, sadly his natural attributes will prevent him from being in the same league - at least when it comes to winning in multiple weight classes - as 2 of the best fighters in modern history, Manny and Floyd.

Floyd had the natural attributes like reach and a perfect defensive style, and Manny had the power which sadly Loma does not. Still a very, very good and entertaining fighter who might be able to get belts at 140 and 147 but probably only from a vacant belt / weak champion.

Think that depends on how good a fitness coach he has he would definitely need to be hitting the weights in honesty If he plans on remaining at 135lbs I think he should get working on that immediately.
Not saying I think Lomachenko will easily fit in at 140-147, but I just don't think its impossible.
140lbs should be his maximum limit imo, but first he needs to bulk up a bit for 135.
