Thomas Muller returned to training at Bayern Munich on Thursday after the COVID-19 positive test that caused him to miss the Club World Cup final.
The all-action attacking midfielder was dealt his coronavirus blow just hours before Bayern beat Tigres UANL 1-0 to be crowned club world champions in Qatar on February 11, forcing him to self-isolate.
After two weeks away from the squad, and now clear of the virus, Muller was back at the club's training headquarters to be put through his paces.
Bayern announced on their website: "Muller was able to train at Sabener Strasse again on Thursday for the first time after a period self-isolating at home due to testing positive for COVID-19.
"Following final medical tests in the morning, the 31-year-old completed an individual session on the pitch alongside team training under the guidance of fitness boss Prof Dr Holger Broich."
Muller is enjoying a stellar season and is one of just six players from Europe's 'top five' leagues to have reached double figures both in goals and assists across all competitions.
He has 13 goals and 11 assists so far, and has created 81 chances in all.
Borussia Dortmund's Jadon Sancho is the only other player from the Bundesliga to achieve the double to date, after 10 goals and 12 assists.
Lagging some way behind Muller in the Bayern ranks is Serge Gnabry, who has managed only six goals and two assists in 28 appearances, figures that are also significantly down on what team-mates Leroy Sane (G: 8, A: 8) and Kingsley Coman (G: 6, A: 11) have achieved.
Gnabry has had more playing time than his attacking midfield colleagues Sane and Coman, and he began the campaign with a hat-trick against Schalke in Bayern's opener.
The former Arsenal youngster was substituted off in the Club World Cup final because of a torn muscle in his left thigh.
Bayern said on Thursday that Gnabry had undergone intensive rehabilitation in recent days and was able to resume training with Hansi Flick's squad.
That may see him come into contention, perhaps along with Muller, for Saturday's Bundesliga home clash with Cologne.
