The thing is, we have better defenders now than Klopp did back then and unlike Liverpool, we had defensive/pragmatic managers for years. So, the defending bit shouldn't be an alien thing for us but that has like disappeared since Conte left.
Someone pointed out above that we had a decent defensive record under Sarri but that's more down to the possession football style of his. We kept the ball a lot and prevented opponents from coming at us consistently. That said, there were a number of games where we looked defensively shambolic.
