Real Madrid's 11 goals in three games since their humbling 5-0 defeat by Barcelona tell you all you need to know about their current mood. However, Santiago Solari's men must overcome a resolute Celta side with a sound home record who came from two goals down to draw 3-3 at Real Betis last time out.
Barcelona's league form has been impeccable in the absence of Messi and if the diminutive Argentine returns they should be unstoppable. The Blaugrauna have scored 12 goals in their last three LaLiga outings and Real Betis are hardly known for their defensive solidity this season.
This represents a tough first league game for new Real Madrid boss Santi Solari, with Real having lost four of their last five, and he is without Varane and Marcelo. In addition, Real Valladolid have not lost an away league game this season, winning their last two. A draw might be the best option in the betting markets.
Rayo Vallecano have yet to win a home league game this season, losing three including 4-1 to Sevilla and 5-1 to Alaves. After four league games without a win, Barcelona have beaten Sevilla and Real Madrid, scoring nine and conceding three in the process, so expect another easy victory here.
Despite the absence of Lionel Messi, Barcelona look to have more quality in the final third and can heap more pressure on Real Madrid manager Julen Lopetegui with a home victory in El Clasico. Expect both teams to score, though, as Barcelona have conceded in their last seven league matches.
Form is certainly with the visitors coming into this game and they sit in the unfamiliar position of being above Barcelona in the table heading into it. Barcelona will be desperate to get back to normality and this should be an open game with plenty of goals.
After four games without victory, Real Madrid will be desperate to return to winning ways, especially with some big games coming up. Los Blancos can normally be relied on for goals at home and Levante have failed to score in just one of their last 14 league games, so expect goals at the Bernabeu.
Barcelona are enduring a slight blip in the league but will be full of confidence after beating Tottenham and can get back on track. Valencia have scored just five goals in seven La Liga games and, after also drawing a blank in midweek, should not trouble the league leaders' defence.
Deportivo Alaves have not beaten Real Madrid since 2000 and although the visitors have endured a lean patch of late with no wins or goals in three matches, Alaves were brought down to earth last weekend at Levante after their fine start, so expect the natural order to resume here with a Real win.
Form favours Atletico coming into this derby and the fact they beat Real in the UEFA Super Cup. Real will be desperate for revenge though and they will be highly motivated here. With both defences not at their best right now and Marcelo missing for Real, expect goals for both sides in this derby.
Barcelona are sure to be champing at the bit after suffering one of the shock La Liga defeats of all time on Wednesday to bottom side Leganes and Athletic Club do not look in the form to stop them after slumping 3-0 at home to Villarreal on the same night.
Celta's matches have been quite high scoring in recent weeks but the same cannot be said for Valencia whose last two matches in the league have been goalless draws. They will look to attack more at home though so expect them to take more chances, with both teams likely to score.
Sevilla are playing with great confidence right now and the goals are flowing so this promises to be a fascinating encounter with Real. The visitors are playing well themselves and with the front men rested, this has all the makings of an entertaining match with plenty of goals.
The match pits top versus bottom in La Liga with Leganes searching for their first win, while Barcelona seek to get back to winning ways. Barca have scored the most goals in the league this season and will be disappointed with their draw on Sunday, so back a resounding reaction from the away side.
