Real Madrid midfielder Toni Kroos has gone into self-isolation following contact with a person who has tested positive for COVID-19, the La Liga club said on Friday.
Real added that the Germany international's tests had come back negative. Fellow midfielder Federico Valverde went into isolation last month before then testing positive.
"Real Madrid C.F. reports that our player Toni Kroos is currently in isolation after being in contact with a person who has tested positive for COVID-19, although all tests carried out on the player have come back negative," a club statement said.
