Based on his interview i think he'll stay this year but actually, for a footballer, it was quite a clever interview and did contain a bit of warning/shot across the barrels to Poch/Levy i.e. match the players ambitions or they're off.
You do realise that neither Levy or Pochettino are idiots. They will do what they can within the financial limitations they have to work under. Expecting Spurs to match Man City, Man U or Chelsea for wages is plain silly.
