Real Madrid already has one goal and the game is still going on. I also don't think that Real Madrid will have a hard time against Sevilla because their performance has decreased in the sense that their rotation has decreased so Real Madrid can freely win it.
The game just started 5 minutes ago Real Madrid scored a goal by Modric, that's great for this match. But now Real Madrid has not managed to add to its score even though the first half is almost finished. My prediction should be right, 2-3 goals for Real Madrid's victory in this match will make the standings safe from the pursuit of Barcelona.
I'm sure Real Madrid will not lose points and control in this match. H2H is ours and it would be great to maintain that unbeaten record. If Real Madrid win, really we will be safer to keep our distance from Barcelona.
