To me, Levante showed nothing special this season. I watched them in their last league match against Rayo and realistically they should have suffered a decisive defeat. Their goalkeeper Navar had a great game and Rayo's strikers kept on missing their chances and only in injury time they managed to score a winning goal with a man advantage. Even with a man advantage they were mostly concerned about defending their own goal and would occasionally threaten from counter-attacks.
On the other hand, Real suffered a defeat in their home match last week against strong Atletico, but managed to play well and players have nothing to blame themselves for that loss. I am aware that Real plays Champions League match this week, which is important to them, but as Arrasate said - no one will be spared today. It would be bad for them to fall behind at the start of the season and I believe they will play for the win today. If we compare the quality of these two teams and their current form, everything is in the favor of the visiting team.
For safety reasons I will pick Asian handicap on Real +0 which will return my stake in the case of a draw
