I agree with you Hectic, he's either very badly advised or he's a complete idiot.
I'd go with badly advised. Based on the interviews he's given, to make a complete 180 and have doubts about being in the first team or whatever other 'concerns' he has makes it seem as if someone's been putting some ideas in his head. I think at that age, you're pretty impressionable still and it's easy to be badly advised if you're not careful. The good thing is that we've already taken a stance with Ravel so if Paul knows what's good for him, he'll stay.
The other issue is how much of this falls on Pogba and how much of this falls on his agent. We're being fed leftovers and scraps from the table so it's a bit hard to judge. Nonetheless, for me personally, I havent seen anything to suggest that Pogba wants to leave. I think he wants to make a name for himself here but maybe he thinks that he won't for whatever strange reason. It seems like Rio is trying to give the boy some perspective and that's really all these youngsters need in this day and age.
The way I see it, it's very easy to be badly advised. People know how to get in these youngsters' heads, say things they want to hear, and tell them what they think they should do in a certain situation without necessarily looking at the consequences. I'm 20 years old now and although it's only a two year difference between from being 18, I can say with full confidence that I've grown up a lot since then and listened to people I really shouldn't have.
Just to be clear, I'm not saying this is as some sort of generalization. Every culture is different but for the most part, I think British and American culture are pretty similar. Similar enough to say that most 18 year olds are pretty naive even though in the US, you're deemed as a legal adult at that age.
That's why I think Rio will play a part in Pogba staying. He can give Paul a sense of perspective that his fellow peers might not be able to offer and it's something that I think will help Paul see the consequences a bit clearer. Not sure how you lot were at 18, but I made some pretty dumb decisions then that were more so, on the whim more than anything. This isn't an excuse for Pogba's behavior. Like I said earlier, it's a bit of speculation but from what I've seen, I think he's being badly advised.
