Football is like that, sometimes it’s the smallest details that matter and we have not been able to control those as much this season,” he said."We won the World Club Championship and without realising it probably lost a bit of rhythm due to that, but we are keen to win back those 10 points.Real Madrid will be without Angel Di Maria and Karim Benzema so Gonzalo Higuain, who has recently been linked with a summer move to Manchester City, is likely to start.Rayo have won their last three games and sit in eighth position, only two points behind a potential Champions League place next season. Equally difficult is the task facing Barcelona.Atletico Madrid are still unbeaten in the league since the arrival of new manager Diego Simeone at the turn of the year, and a full house of 54 000 is expected to attend a duel that always promises goals and spectacular football.Third-placed Valencia host Sevilla in the pick of the other games.
