City and Real Madrid are through to the QF, it was pretty routine for Pep's men, but it was far from comfortable for Real Madrid and they just narrowly progressed to the next round, i reckon that they would improve, and they have to because the games are going to get tougher from now on. The four teams that have progressed thus far would wish to avoid each other in the next round, because they are the biggest teams left in the competition and a tie between any of them would be a cracker with no clear favorites.
