Sparks flew as Gerard Pique and Luis Suarez squared up in training ahead of Barcelona's Champions League clash with Manchester City.
Centre-back Pique took exception to something Suarez did and the pair were involved in a confrontation, but the pictures suggest Suarez was immediately apologetic.
Neymar and Lionel Messi stepped in, and the dispute was quickly resolved with Pique and Suarez all smiles afterwards.
Wednesday night's match sees the return of Pep Guardiola, the man who led Barca to 14 trophies in four glittering years at the Nou Camp. He won 10 trophies during his 11 years at Barca as a player.
Barcelona won their opening two matches in Group C, hammering Celtic 7-0 and Borussia Moenchengladbach 2-1.
They have met City four times in the last three years in the Champions League - winning all four matches.
