Just an opinion. I might be totally wrong, but for the Spurs game, I think I would start with Gomez at RB. TAA can be subbed in later on (strategically), but considering we are playing away from home and we've displayed time and again over the past 10 games that we cannot keep hold of the ball and we will cause countless turnovers in the middle of the pitch, I'd rather see Joe brought in at RB. He can sit a bit lower than TAA does usually and keep an eye on that Sessegnon, Son, Perisic, and Davies left flank. I know Son is a doubt for that game since he came off with a head injury last night, but still.
One thing we know for sure is Conte likes to crowd the midfield and play a 3-5-2 or 3-4-3. I think that if Son is indeed out of the game then a 3-5-2 is more probable since they will also be missing Richarlison and Kulusevski. Whichever one it is, it does not bode well for our midfield since we cannot keep hold of the ball if our lives depended on it and it's not about to get better, away from home, against a team who adds an extra 2 bodies in that area. That's why I'd like Gomez to be brought in instead of TAA. They will surely attempt a lot of runs down both sides and cross the ball to Kane and those attempts will also rely on them winning the ball in the middle of the park (which they will). We need someone with pace and strength to battle their crosser for a good portion of the game. This will also enable Konate to focus on the more central threats rather than mop up behind TAA like the right sided center halves have had to do all season now.
