As Barcelona's star-studded array of players return from their respective international camps, it is pivotal to the Catalonian outfit that the remarkable run of form they embarked on prior to the World Cup qualifiers is maintained.
Since losing to Cadiz in early December, Blaugrana haven't lost in La Liga for 18 matches, winning 15 and drawing just three - making it the current best unbeaten run across all of Europe's top five leagues.
Due to this sensational record, Ronald Koeman's side have sliced the deficit between themselves and league leaders Atletico Madrid and now sit just four behind Atleti with 10 games to go.
In their last outing before the international break, Barca marked the start of Joan Laporta's presidential reign in style, as they sensationally thrashed a well-organised Real Sociedad side 6-1 at the Anoeta Stadium.
Awaiting Barcelona next in their battle for the title is the visit of bottom-half strugglers Real Valladolid to Catalonia on Monday, and Sergio Gonzalez Soriano's side will be desperate for a season-defining upset.
Los Pucelanos currently sit in 16th place and just four points clear of Eibar in the bottom three - a far cry from their comfortable mid-table finish last season - and should they continue to drop points, danger will ever so slightly begin to creep closer.
In a game that could have significant implications at both ends of the La Liga table, this one has all the makings of a captivating clash in Catalonia.

Barcelona 5-1 Valladolid

A five-star performance from Lionel Messi saw him record two goals and two assists as Barcelona thrashed Valladolid 5-1 at the Nou Camp to return to the top of the La Liga table.
In an action packed first 15 minutes, Clement Lenglet gave Barcelona the lead before Valladolid equalised through Olivas Alba, but Valladolid's night was soon over before it had even started.
After playing through Arturo Vidal who restored the hosts' lead, Messi inevitably extended it with a goal of his own, scoring the 50th free-kick of his career to close out the first half in style.
The following 45 minutes were very much business as usual for Blaugrana. Emulating his previous heroics, Messi was on hand to provide another goal and assist combination to provide his side with an unassailable lead.
After exquisitely controlling Ivan Rakitic's through ball and coolly converting to complete his brace, the Argentine slipped through Luis Suarez two minutes later who made no mistake in making it five.

Despite the victory in Valladolid, Barcelona were unable to complete a famous comeback as their Clasico rivals went on to win their 34th league title.
