Spurs had a grand chance two years ago, as did Arsenal, and they blew it. Right now, they are a great team, but their chance of winning anything is almost as good as gone.
There might be a Europa League opportunity, but they need a much bigger squad for that and probably another coach. The physical stuff one. Like stamina and so on. Because it's clear that Poach simply can't ready the players for Thursday/Sunday routine. Of course FA cup, League Cup is also a possibility. But can they keep their core for that long. City can go for Kane, Real as well, since Benzema is getting old and they need a CF, with Morata gone and Spurs would prefer to sale abroad, this move does make sense next year or in two years time.
