Sunderland midfielder Sebastian Larsson feels they're improving defensively.
Larsson was happy with the stalemate earned at Leicester City.
Larsson said: "We look like a tough team to beat again; I think that is the difference compared to earlier in the season. In the past we might have also come into a game like Saturday's and not created much but we created enough to win it comfortably.
"It is of course disappointing when you do that and don't take the three points, but sometimes you have just got to take the positives and move forward.
"We haven't been too worried about our upcoming games but it was important to pick something up (at Leicester) - particularly after the last international break because everybody knows what happened. They are great games coming up and we have picked up points against the big boys before, so why not do it again."
