Arsenal manager Mikel Arteta tested positive for COVID-19 on Thursday night, according to a statement on the club's official website.
In the statement, Arsenal detailed the measures taken to protect those who had been in close contact with Arteta and prevent further spread of the virus:
"Arsenal personnel who had recent close contact with Mikel will now self-isolate in line with Government health guidelines. We expect this to be a significant number of people from Colney, including the full first-team squad and coaching staff, as well as a smaller number of people from our Hale End Academy which we have also temporarily closed as a precaution.
