Yeah, their defence in particular looks dodgy, especially now they don't have their first choice keeper. Let's be honest, this is the worst Chelsea team for a long time, and even Norwich gave them trouble at the back at times. Which is weird, because that's the area that they looked strongest last season.
I still maintain that their problem will be their lack of depth in a season where they've not given their best players a proper rest in the summer. You could say the same with us playing Mahrez and Jesus so soon after their international tournaments, but the difference is that we can give those players a rest and bring in someone just as good if not better. If they want to give their front three a rest, they have to play Lallana, Origi and Shaqiri. The idea that they're going to win 6 trophies is laughable when we all saw them basically throw two away on purpose last season because they didn't have the squad to cope with four.
