Arsenal head coach Mikel Arteta has been diagnosed with coronavirus this evening.
In a statement, the club said: “Our London Colney training centre has been closed after head coach Mikel Arteta received a positive COVID-19 result this evening.
“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.”
The expected shift in UK policy came as Donald Trump dramatically escalated the US response to the coronavirus pandemic, slapping a travel ban on continental Europe.
The suspension of travel between the United States and Europe – excluding the UK and Ireland – will last for 30 days starting on Friday.
Mr Trump made the announcement in an Oval Office address to the nation, blaming the European Union for not acting quickly enough to address the outbreak of the virus and saying US clusters were “seeded” by European travellers.
Chancellor Rishi Sunak played down the prospect of the UK imposing similar travel restrictions, saying “the evidence here doesn’t support that”.
A Cabinet minister, who has not been named, was self-isolating while awaiting a test result after coming into contact with health minister Nadine Dorries.
Ten people have so far died in the UK after contracting coronavirus.
