He is deciding on his future. There are many clubs (mainly from England) interested who have informed about him, currently these 3 are 'in the lead' to sign him: Manchester United, PSG and Liverpool. (He didn't want to name the other clubs)
He likes the PL. MUFC have got a trainer who likes him, they'll probably play CL and they can offer him good wages. They have the most plus-points to sign him.
PSG (Thijs is close friends with Zlatan since his Ajax days so knows a bit about PSG) have left a good impression on him, Thijs has been told by his sources. Laurent Blanc left a good impression on him and is a nice man, the owners are nice people too. They have less plus-points but they do have alot of money - Memphis could choose for financial stability if he wants. They've got a good team and are serious contenders for the CL.
Liverpool. They play in the PL and he might fancy a lesser contract with more gametime. If he decides that this is the most important thing so he might choose them as his first step. He doesn't think he will choose for them since they don't have CL, Rodgers hasn't won anything in 3 years now so he might have doubts about his long term future there - a new trainer might not fancy him.
