I agree with you. Real Madrid will go all out to beat Barcelona. I think this will be an important moment for them because if Madrid is able to beat Barcelona then they will be 11 points ahead of Barcelona in second place. This will further secure first place for them.
No doubt Real Madrid will try to beat Barcelona with their best. Sure, it is an important match for Real Madrid, winning the match may secure their position in the 1st place. If Real Madrid win the match, the point gap will be 11 points and it will be quite difficult to catch by Barcelona because there will be 5 remaining matches only.
The Champions League will be played on May 1. That means Madrid will have sufficient rest time after playing Barca.
Indeed. The match will be in the early of next month, there is enough time to take a rest. I think it won't be a problem to play all out against Barcelona before the match against Bayern Munich in UCL.
Yes, Madrid currently leads the standings with 78 points. Barcelona is right behind them with a difference of 8 points. Madrid has met Barcelona twice this season, and always won. Madrid will stay away and increase their chances of winning if they are able to beat their rival again in the next match.
They are leading with 8 points but it may be not secure if Barcelona can win the match. The point gap will be 5 points, Barcelona may have a chance to catch Real Madrid if Real Madrid lose again the next match. Real Madrid should avoid this possibility, they will try to win the match. So, I agree that Real Madrid chance to win the title is higher if they win the El Clasico.
