Coates is foreign. And is a bigger risk. That has nothing to do with more potential. If Dalglish had the opportunity to sign a player who was foreign and more talented, or whom is english and slightly less talented, he would sign the englishmen first, because the risk of adapting is much less. Not good reasoning.
I am a Liverpool supporter. You are a United supporter. If my opinions on Coates are void, then how the hell are your opinions on Jones valid? Hypocrite.
You seem to have difficulty understanding the difference between better or more talented player, and more accomplished player.
Jones is a 6 foot tall centreback. Undersized. Sure John Terry has been a great player at the same height. But a player, if all other things are equal stands at 6 foot 6, they are likely to be a much more dominant player.
I've never seen any of the players you mention go on such a run and at the end of it have the composure to provide such a quality pass (Maybe Lucio). So you are talking bs. If Coates has the vision and ability to provide such a through ball after such a gut bursting run, it's pretty safe to say he has the ability to do it stationary from deep in defence under much less pressure. Also I regard Lucio as a ball playing centreback. He has the ability to make head scratching decisions, but his ability on the ball is not in question.
Bottom line, Coates has good speed for his height, is tall and strong, composed and quite good on the deck (I was responding to your original comment that Coates is nothing on the deck compared to Jones, which has been clearly proven wrong). Jones is the more accomplished of the two by virtue of playing at a higher level, but if you are looking at talent, Coates superior physical ability gives him the potential to be a much better player. But that's still just potential, realising it is a different story. Not every player reaches their potential.
