Zlatan likes living in nice cities, all his destinations like Milan, Turin, Barcelona, Paris, Amsterdam now LA are favorable destinations for anyone in this world
Malmo and Manchester are the only cities that seem like a downgrade and it doesn't surprise me one is where he started and the other was the only club willing to pay his wages he was demanding.
he also doesn't feel like he owes anything to Malmo so why would he choose them over LA.. not like the swedish league is all that great compared to MLS (which is also not all that great)
