I'm in the same boat, I've torn Sissoko to shreds in the past. He barely looked a footballer at times for us last season, just totally clumsy on the ball and even when he would manage a powerful run he would give it away 90% of the time. Probably one of the most frustrating players I've ever had to watch as a Spurs fan, but this season it's a different story .. either Pochettino has worked his magic, or Sissoko has just settled at the club now. Either way he's going to be so vital this season because without him coming good we'd look very light in midfield.
Winks has been great, he got quite a lot of criticism on here but there's always been a player there. He's now gone to the Bernabau and the Nou Camp and put in two very mature performances, he's a proper reliable central midfielder and I think will be starting for England at Euro 2020.
