What concerns me is that midfield especially isco and modric, they are truly unique and not type of players we come across. Ronaldo of course is a different breed in the box but usually we have no concerns in the box, it's them guys outside it. It Is a good thing carvajal is missing, hope he doesn't recover in time. It's a tasty and an intriguing tie. I'm confident of our ability, they got plenty to fear as well but at the same time so do we.
