Arsenal have closed their Hale End academy following a positive coronavirus test from a member of staff.
The academy in east London is separate from Arsenal's senior training facilities, which are situated at London Colney.
"We can confirm that a member of staff from our Hale End Academy has tested positive for COVID-19... and immediately left the site to self-isolate," Arsenal said in a statement.
"As a consequence, six other members of staff are now self-isolating ... Our Hale End Academy will now be closed on Thursday for deep cleaning.
"The health and safety of everyone on all our sites is our paramount concern.
"No members of our men's or women's first team squads have been affected."
The news follows senior Arsenal player Kieran Tierney being ordered to self isolate for 14 days after coming into contact with Scotland team mate Stuart Armstrong, who tested positive for the virus.
The Gunners did confirm that Tierney had socially distanced himself away from Armstrong at all times and that he has broken no rules in relation to Covid-19 protocols.
Tierney responded by admitting disappointment and frustration at the measures, as it now means he will miss the crucial trip to Manchester City following the international break.
He said: "I'm so disappointed and frustrated to be in this situation. I have adhered to all regulations and made sure I was socially distancing from my team mates in the hotel.
"I've also tested negative. I know Arsenal and the SFA are now in discussions with the Scottish authorities to gain a further understanding."
