Barcelona have the chance to go top of la liga for the first time since October in a Copa del Rey final dress rehearsal when they visit Alaves on Saturday.
Alaves edged out Celta Vigo on Wednesday to reach the final for the first time, whilst nine-man Barca had to survive a second leg onslaught from Atletico Madrid in midweek to make a fourth straight final. However, Barca's quest for a second treble in three seasons faces more severe tests this week as a visit to Mendizorroza is followed by a Valentine's Day trip to Paris Saint-Germain on Tuesday in the Champions league.
The champions trail Real Madrid by a point, who also have two games in hand, but, with Madrid not in action until later on Saturday at Osasuna, victory will take Barca top for a few hours at least for the first time since October 22. Barca boss luis Enrique has almost a fully-fit squad to choose from as Sergio Busquets and Andres Iniesta made their return from injury as second-half substitutes in midweek, whilst Neymar returns from suspension.
"We are delighted that Busquets and Iniesta have recovered," said Barca midfielder Ivan Rakitic.
"They are very important players and (having been out) they can give even more of what they bring to the team now."
However, Enrique has followed a strict rotation policy throughout a demanding fixture schedule in January and February so the likes of Gerard Pique, Jordi Alba and Sergi Roberto could be rested.
Real return
Madrid are in action for the first time in two weeks when they face rock bottom Osasuna, who are still without a home win all season.
The European champions' clash at Celta Vigo last weekend was called off by wind damage caused to Celta's Balaidos stadium.
Zinedine Zidane's men now face having to play half their league season in just over three months.
However, the break has allowed Zidane to recover a series of important players from injury with the visit of Napoli in the Champions league also to come on Wednesday.
Full-backs Marcelo and Dani Carvajal have returned to training along with luka Modric, James Rodriguez and Pepe leaving Gareth Bale as Madrid's only injury absentee. Toni Kroos will be missing, though, through suspension.
Despite languishing eight points adrift of safety at the bottom of the table, Osasuna have shown signs of improvement since Petar Vasiljevic took charge in January.
Osasuna have taken the lead in each of their last three games and captain Oier Sanjurjo believes they are on the verge of turning their season around.
"We are strong. We have begun to show that we are competing," he said.
"What we want is for all that to come together for once and be rewarded in a win."
Third-placed Sevilla need to spoil Jese Rodriguez's home debut for las Palmas on Sunday after joining his home town club on loan from PSG if they are to remain on Barca and Madrid's coattails in the title race.
Atletico hold the upper hand in the battle for the fourth Champions league spot, but six sides are separated by just seven points.
Two of them go head-to-head today as Espanyol host Real Sociedad, who can leapfrog Atletico with a win.
Atletico aren't in action till Sunday when they host Celta Vigo at the Vicente Calderon.
Silva’s impact felt
It seemed Marco Silva had taken on a near-impossible job when he was hired as manager of Hull at the start of January.
The promoted club from northern England was up for sale, in last place in the Premier league and planning to sell some of its best players. Money was tight, fans were disgruntled and a squad short on big names had been struck by injuries in key areas.
Silva, a 39-year-old Portuguese coach labeled "Mini-Mourinho" by some after his illustrious coaching compatriot, was new to the English game and was facing a tough and grueling immediate run of matches across three competitions.
Silva has worked wonders in the transfer market and on the field.
Operating under financial constraints, he saw key midfielders Robert Snodgrass and Jake livermore sold from under his feet and reacted by making seven signings - predominantly players on loan and rejects from bigger clubs. Striker Oumar Niasse, for example, arrived from Everton, where he had made five appearances and not scored a single goal in the past year; winger lazar Markovic (from liverpool) and Omar Elabdellaoui (from Olympiakos) were among others looking to relaunch their careers.
On the training ground, Silva worked hard on team shape and organization, with defender Curtis Davies saying the coach literally dragged players into the positions he desired. Days off were canceled. Silva was hard, but fair.
His impact was been astonishing.
Hull has won all four of its home matches under Silva, having failed to win any of its previous five at KCOM Stadium. Among the defeated teams were some stellar names, Manchester United in the league Cup and liverpool in the league last weekend. Hull also ground out a 0-0 draw at United in the league and was regarded as unlucky to lose 2-0 at runaway leader Chelsea, when midfielder Ryan Mason fractured his skull.
