Real Madrid against Sevilla on Sunday could have been a key game in La Liga's title race but instead it will decide the extent of Madrid's lead and how worried Sevilla should be about finishing in the top four.
A Real Madrid win at the Ramon Sanchez Pizjuan would send them 15 points clear of Sevilla, who at the end of January were only five points behind the leaders, with a game in hand.
But a disappointing run of three wins from 11 league games has seen Sevilla fade away from the fight for the title and drift into the scrap for the Champions League places as local rivals Real Betis and Atletico Madrid look to take advantage. A 4-2 victory over struggling Granada last weekend was much-needed for Julen Lopetegui's side, even if it required two dramatic late goals in injury-time, Rafa Mir and Papu Gomez leaving it late to snatch the win.
Sevilla will be hoping to build on that result but they have a difficult run-in, with the game against Real Madrid coming before visits to Villarreal and Atletico Madrid ahead of a final game at home to Athletic Bilbao.
Real Madrid will be flying high on the back of their sensational victory over Chelsea in the Champions League quarter-finals, although being taken to extra time at the Santiago Bernabeu may also take its toll.
Ferland Mendy and Marcelo are both struggling with injuries while Carlo Ancelotti could rest the likes of Luka Modric and Karim Benzema, who played the whole 120 minutes on Tuesday.
Madrid's progress in the Champions League, combined with their considerable advantage in La Liga, means Ancelotti has the option to rotate in domestic games until the end of the season, which could give Sevilla a boost.
"We're in good form," said Ancelotti last weekend. "We have an advantage in La Liga and we have to keep going."
