New coach Felix Magath has returned from isolation after contracting the coronavirus as he conducted training at troubled Bundesliga club Hertha Berlin on Thursday. “Welcome back, boss,” Hertha tweeted, showing Magath at the day’s closed session after testing negative. Magath was appointed Hertha coach on March 13 but tested positive a few days later and missed Saturday’s 3-0 win over Hoffenheim, with assistant Mark Fotheringham in charge of their first win of the year. Hertha are third-last, and their next match is after the international break on April 2 at third-placed Bayer Leverkusen.
