Barcelona players expressed displeasure towards their manager Quique Setien following their 2-2 draw against Celta Vigo in their La Liga meeting last weekend.
Barcelona's latest struggles have led to rumors that the manager is in danger of losing his job.
Although Setien conceded it is normal to have occasional differences, he insisted the squad is unified despite the apparent issue with Sarabia and the fact certain publications have suggested the head coach himself has a strained relationship with Messi.
When asked how he would solve any issues similar to those appearing at Barca, he added: "I wouldn't tell you, and I would try to solve it naturally in our camp, which is the dressing room or the training session".
But ahead of the crunch clash with Atletico, Setien has at least been handed a show of support from club figures who visited his home on Monday, according to reports in Spain.
