Fair enough, thanks and no problem.
I think I can see your perspective, and I get how you feel really. These are some bloody good defenders we're talking about here and the kid is only a novice at this level. These labels are not only disrespectful to the older guys but also putting unnecessary pressure on a young man. In fact, I reckon a whole host of people who haven't bothered to post probably felt exactly the same way. So kudos for speaking up.
The only thing is, is that the bunch of us are not all trying to say he'll be good like they were (some may have been tbh I haven't checked). We're trying to simply reassure some other posters and probably ourselves that his height isn't an issue, particularly in the notoriously physical English league environment. And what most people have realised is that the best way to do that is to point out examples of other players lacking in height who nonetheless turned out to be successes.
As an example, it's not so much, 'He'll be the new Cannavaro'. It's more, 'Well Cannavaro became world class and he wasn't even 5ft10, so there's no reason why Garcia being 5ft11 should be a limiting factor.'. We could be more pragmatic and say he might be as good as the similarly heighted Nedum Onuoha or maybe even Wes Brown if we're ambitious, but that wouldn't allay people's fears that he can make it at City level. I am certain plenty of others in your position would have found that reasonable.
I personally was only pointing out that we hadn't made the comparison with Carvalho as he is a guy who was a great success in England in spite of apparent shortness. Most of the other examples hadn't played in England so you could always make an argument based off that fact to deny those examples. I'll admit my language, particularly the word comparison was potentially misleading. But I'd like to assure that it's not about what you think it is, even though everything you said was totally accurate within the assumption that it was what you were thinking about. It's about trying to disprove his height being a reason he'll fail in England.
Sorry for any misunderstanding.
