I think you might be a little bit mistaken here. Unai Emery left Villarreal for Aston Villa and not Valencia.
I don't think Valencia, Mallorca, Elche and Osasuna are strong teams for Real Madrid during their February schedule. So Real Madrid shouldn't have any problem getting all those points in the end. Only Atletico Madrid might cause problems, but Atletico Madrid is also unstable so far. So I can say that Real Madrid will lock in 3 points today at home even though they only won 1 point in the previous match.
This might be easy to say but with Real Madrid having Champions league in between some of these game, I see Ancelotti probably looking at rotating his squad to be Able to cope with the fixtures. Madrid second eleven should also be capable of winning this matches but the cohesion can affect them.
The game against Valencia will be easy on paper but considering Madrid last matches, Valencia might want to pull off surprises. But i will also predict a win for Madrid but won’t be an easy win probably a goal goal game
