Thiago Alcantara has resumed outside training but is yet to re-join his Bayern Munich team-mates as the midfielder continues to recover from a thigh problem
Thiago sustained the injury during the club's mid-season training camp in Qatar in early January.
As a consequence, he was absent when Bayern returned to Bundesliga action with a 2-1 away win over Freiburg on Friday.
Head coach Carlo Ancelotti has previously said he hopes the 25-year-old midfielder, who has scored three goals from 22 appearances in all competitions this season, will be available for the first leg of Bayern's Champions League round-of-16 tie against Arsenal on February 15.
Thiago joined Bayern from Barcelona in 2013, following then manager Pep Guardiola from Camp Nou to the Allianz Arena.
He has won the Bundesliga title in each of his three seasons at the club, having lifted four La Liga trophies with Barcelona.
