Barcelona's resurgence under Xavi will be put to the test when they travel to face Real Madrid in El Clasico.
The Catalan side extended their unbeaten run to eleven games with a 2-1 win over Galatasaray in the last 16 of the Europa League in midweek.
Xavi's men are also closing in on Sevilla in La Liga, with last weekend's 4-0 win over Osasuna moving Barcelona to within five points of the Andalusians in the table.
Here's how Barça could line up as they go in search of a momentous victory.
1. Goalkeeper & defenders
Marc-Andre ter Stegen (GK) - Has made a couple of high-profile errors this season, but he appears more assured under Xavi.
Dani Alves (RB) - A remarkable athlete for being 38-years-old, often moving infield to allow Dembele or Traore to hug the touchline.
Gerard Pique (CB) - The Spain international has vast knowledge of this fixture, experiencing both the extreme highs and lows.
Eric Garcia (CB) - Has dislodged Ronald Araujo in the Barcelona backline in recent weeks.
Jordi Alba (LB) - Has proven an excellent servant for Barcelona, consistently producing numbers in the final third.
Sergio Busquets (CM) - The Spaniard was talking up his former teammate-turned-coach, saying Barcelona are 'more complete' since his arrival.
Pedri (CM) - Netted a gorgeous goal in the midweek win over Galatasaray, underlining his technique and composure.
Frenkie de Jong (CM) - A real threat breaking forward from midfield, developing a knack of scoring important goals recently.
Ousmane Dembele (RW) - Turned jeers to cheers at Camp Nou with a scintilating display against Osasuna last weekend.
Pierre-Emerick Aubameyang (ST) - Made quite the impact since joining in January, netting seven times in as many games.
Ferran Torres (LW) - Has proven a shrewd addition under Xavi, scoring or assisting in all but four games since mid-January.
