Real Madrid vs AS Roma prediction

This Tuesday at 19:45 GMT in the Champions League play offs, Real Madrid will host AS Roma for the 2nd leg. For me it's clear that Real Madrid will qualify, but the question is: Who will win this match now? It's possible that Real Madrid will play defensive and keep the goals to a minimum, maybe 0-0 or AS Roma could slip one goal at the end making them winners for this match, because they will not go that easily. And there is the bookies prediction, favoring Real Madrid with the odds of about 1.40.  The way i see it, Real will start to play defensive for a 0-0, AS Roma will score one goal and Real will be forced to mark one goal to be safe or Real will go nuts scoring over 3 goals and AS Roma will be forced again to at least score one goal. In any case both teams will score, making this my prediction for this great match.
