Another thing I asked about Isaac is the place from which he came, and how his background formed as a person and a player.
He grew up playing football in the streets on the outskirts of Stockholm and there is still an element of that for his gameplay now, with the way the ball caresses and his ability to dodge.
His parents had to flee to Sweden from Eritrea and start a new life there, which tells you what they made and how difficult they were.
There is a little steel about him as well – perhaps not when you look or talk to him, but definitely when he is outside the field.
The aggression is part of his game, such as his skill on the ball or his intelligence to drop the depth or manufacture of defenses.
He can deal with himself physically, and he is very comfortable in dealing with speculation about his future as well.
I think he finds that it is exciting for people to say that other clubs want him because of the quality of his performance, but nothing from this hadith comes from him, and he certainly does not let him affect his shape.
It is clear that he is an ambitious man who wants to play in the Champions League, but like Newcastle fans who love him, I hope he can achieve these goals in St. James Park.
I ended our conversation by telling him to continue doing what he was doing, and he was displaced that nine -year contracts seem to be fashionable for the attackers at the present time.
It will be great for seeing him as long as that and help the team win some awards, but I think we will have to wait and see whether he listened to me or not.
