It had been thought that Rafinha would not be included for the club this season and an exit was imminent after he was not handed a squad number for the 2020/21 campaign, but it appears that Koeman has made a u-turn on his future.
Rafinha, 27, had been on a season long loan deal at Celta from the Camp Nou – where he made 90 first-team appearances – and he spent the second half of the 2017/18 campaign on loan at Inter, but has now returned.
Rafinha played 30 games for the Galician club last season – 29 in La Liga and one in the Copa del Rey – scoring four goals and providing one assist.
There are four absentees for the Blaugrana: goalkeeper Marc André Ter Stegen, striker Martin Brainthwaite, defender Samuel Umtiti and midfielder Matheus Fernandes are all unavailable, as per Diario AS.
Five players from the B team squad are included on the list – Riqui Puig, Iñaki Peña, Ronald Araujo, Arnau Tenas and Mingo.
