1. I doubt it matters that much to him, he's still at an early stage in his career and game time is more important than money.
2. So what? He probably prefers Martinez to Mourinho, you should've seen his goal celebration on Sunday when he ran up to Martinez and hugged him. In his eyes, Mourinho is someone who signed yet another striker (Eto'o) to replace him; whereas Martinez is someone who values him.
3. Again, so what? Jamie Carragher grew up supporting Everton, but is now a Liverpool legend.

3) So? That doesn't mean playing for his boyhood club at the highest level doesn't appeal to him. Granted it isn't a big factor but you cannot deny that it is one
