Both out injured.
Bellerin and Tierney are injured. Probably Maitland-Niles at right-back who is very vulnerable defensively as well.
If that's the case then we need Son targeting right back all game. We haven't used width enough in the 3 games we've had. On Sunday you could have thrown a blanket over Lucas, Son, Kane and Lamela they were that close. We need width so whoever is playing off Kane, whether thats Eriksen, Dele, Lo Celso or anyone else can move into space left.
The midfield battle will be interesting. Ceballos looked good vs Burnley but was a passenger vs Liverpool. If Ndombele is fit then they'll have a problem containing him. It's a tough one between dropping Winks or Sissoko. Winks is a good passer of the ball and will start attacks, but Sissoko is very good at driving up the pitch with the ball and is hard to stop once he gets going.
