Spurs performances this year haven't been all that great and it shows as Pochettino has been tinkering. Much as we all like to think they have a settled squad and team the tactics Spurs have used for the first 4 games are way different than anything they've done before. Essentially they're using two strikers with Kane and Moura being pared, somewhat of an old school little guy/big guy combo, while rotating between Dier and Dembele at the base of midfield in a super lopsided 4-3-3 or 3-5-2 where Trippier a lot of the time is solely responsible for the right hand side. Trippier is not very good defensively. A lot of this leaves open questions, does Poch see Lucas as a better striker than Kane? Is Kane even really healthy? Does moving Alli into midfield take away from what he does best? Is Dembele basically washed up at this point? Maybe Son's return will solve all of this. I somewhat doubt it but it's a really interesting set of questions.
In my mind the worst case scenario should be a scoring draw. Otherwise assuming Keita is starting then between him, Mane and Robertson we really should be able to get at them down our left side. We should be able to keep them at bay defensively, they're nothing great going forward so far this year. We should be able to win this one.
