“Teams are coming here and sitting back and it’s difficult to break them down, because it’s so tight,” the England midfielder told Chelsea TV.
“We need to get on the training pitch and work on trying to get balls in behind and work on playing against a deep back four.
“We need those clever movements in behind, even though they are deep. One of those diagonal balls over the top, like you see Barcelona do a lot.
“We need to work on that. It’s about having patience as well, because it’s so frustrating at times. You can’t get that space to open them up.
“I think we need to get used to it, because we’re playing well at times, so teams are going to come here and do that – and away as well.”
