Real Madrid should control the games against Manchester City and as possible have dominance in midfielder area,
Well, i don't think Real Madrid are going to control the game against Manchester City, in last season's SF when the both sides squared off, City controlled the game for the both legs, and still did not win. I don't think any football side can control the game against Manchester City, you just have to come up with a different game plan, and last season Real Madrid chose to hit City on the counter attack, which they were successful at.
Having said that, i don't expect Real Madrid go seek complete dominance against City, they will be patient and wait for their time on the counter attack, but i think it is City that would progress to the final this time around, they definitely must have learnt their lessons from last season and i am pretty sure they'd not allow it to repeat again this time around.
It is not possible for Real Madrid to control and donate the game against Manchester City, but what exactly do we mean by the term Control? Real Madrid is not a team that plays on a lot of possession. That is not their way of playing and they are not at their best at it. They will let City play far forward and will watch for small individual mistakes and then strike on the counter. It is often said of Real Madrid that they can only counter, but of course they can do much more than just counter. The counter part has been elevated by art by Real Madrid and last year things went wrong for City in a completely different way. What happened then in the match Real Madrid - Manchester City is still incomprehensible.
