"We will need to proceed with caution because a bad result can mean that you suddenly go from having a very good year to not such a good one", Gerard Pique warned this week at a sponsor's event, where the talk was of Chelsea rather than Eibar.
The La Liga match between Eibar and Barcelona will be broadcast live on beIN Sports.
Atletico Madrid's chances of a league challenge have suddenly been reignited, having lost just one league game all season - at Espanyol (proving to display a formula for halting La Liga's best).
Valverde's team has now equalled a club record by going 31 LaLiga games unbeaten and enjoy a 10-point lead at the summit, at least until Atletico Madrid hosts Athletic Bilbao on Monday (AEDT). They played with high intensity right from the first whistle and were on top for the first 15 minutes of the game.
The game-winner was scored by Luis Suarez - his 17th in 21 league matches - in the 16th minute after the Uruguayan striker was played through by an inch-perfect ball from Lionel Messi. Once again, Messi set Suarez up to take the ball around the keeper.
The Catalan team will arrive to Eibar on Saturday on the back of two consecutive league draws, including a 0-0 stalemate at home to Getafe on Sunday.
Firmino wants Liverpool to make Porto suffer
I don't like talking about the round after the round you are playing, in fact I hate it. There were a total of 11 goals in Porto's last two UEFA Champions League home games.
However, the Chilean was sent off midway through the second half, stupidly picking up a second yellow card for kicking the ball away.
Not many teams in the world will cost €300 million to assemble, but that's how much Barcelona have spent on Ousmane Dembele and Coutinho. Those two wins have come in the last two matches.
Lionel Messi brilliantly found Luis Suarez for Barcelona's opener.
After a slow start, the Catalans quickly settled in their rhythm and the opening goal subsequently followed, which was converted by Luis Suarez after 16 minutes, 0-1. During that time they have beaten third-place Valencia and embarrassed Sevilla by putting five past them last month.
Ernesto Valverde's side will have one eye on their European game at Stamford Bridge, scene of one of the club's most famous nights as they earned a dramatic late draw to advance to the final en route to the treble in 2008-09.
Even after Orellana's red card, Eibar still posed a threat. However they cast off their shackles with an exciting attacking display to defeat Copenhagen 4-1 away from home in the Europa League showing that when they put their mind to attack, they can do so. They didn't get their reward here but they may still get it at the end of the season.
