After none of these games you go into the dressing room and think, "Now we know how to beat Manchester City", because there is no real way, no one thing that you have to do. I suspect he won't change and will hope Klopp's side are exhausted from the midweek trip to Napoli.
"Not 100 per cent sure, he had a back spasm. But that's no problem; if you work hard, you earn it".
