Ronald Koeman explained that he is generally against player rotation, especially at this early stage of the season, in a press conference before Barca's game against Celta Vigo on Thursday night.
Barcelona ran out easy 4-0 winners against Villarreal in their first league game of the season last time out off the back of an Ansu Fati brace and a Lionel Messi strike.
Celta Vigo have beaten Barcelona as recently as 4th May 2019, when Maxi Gomez and Iago Aspas scored in a 2-0 win at the Abanca Balaídos.
