Arsenal manager Mikel Arteta has tested positive for coronavirus, the Premier League club confirmed late on Thursday night.
The Gunners were already in quarantine, with their game against Manchester City on Wednesday called off, after they had been in contact with the Olympiakos owner, Evangelos Marinakis, during a recent Europa League game. Marinakis has since tested positive for covid-19, too.
"Our London Colney training centre has been closed after head coach Mikel Arteta received a positive COVID-19 result this evening," Arsenal said in a statement.
"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."
Arteta said: “This is really disappointing but I took the test after feeling poorly. I will be at work as soon as I’m allowed.”
