Ancelotti and his players know they got no luck in La Liga and comparing Barcelona they just need a miracle to win the title of La Liga what's why I think they focused on the champions league more than anything because they know intestine of using the potential for La Liga where they got no hope, they can use this potential in the champions league and get better results there.
Agreed, real madrid didn't have luck in la liga. it's quite better for ancelotti to focus into the remaining match that can be won by real madrid. Madrid is still having copa del rey and UCL. Ancelotti just never need to think intensively about la liga. Just continue and play. If real madrid will be lucky enough and barcelona will be slowing down.
Real madrid just need to continue to win the remaining game in la liga. There's no need to think the club will be able to win or not. The match against celta gonna be another easy match for sure. It would not surprise me to see that if real madrid will able to take full points against celta. Ancelotti will think about what kind of best strategy for the club.
Ancelotti is now trying to divide its focus into the some competitions which are also very important for real madrid at this moment.
