Arsenal

Mikel Arteta revealed Arsenal had been forced to close their London Colney training ground after reporting a 'few cases' among players and staff following their 2-0 victory over West Ham United.

Brentford

The Bees have 13 cases among players and staff – the club are now calling for a circuit-breaker szhutdown to help clubs recover. Their training ground has been closed and as a result their trip to Southampton on Saturday has been postponed. 

Leicester

Manchester United

Case numbers are currently unknown but a large outbreak saw their game with Brentford postponed. Calls to have Saturday's game with Brighton to be postponed were accepted on Thursday, and it has emerged that United would have had only seven available players for that game such is the impact of the outbreak. Their training complex is closed until Tuesday at least, in order to reduce the risk of transmission.

Brighton

Norwich

Manager Dean Smith was facing an anxious wait to discover the full extent of the outbreak at the club. Josh Sargent, Lukas Rupp and Pierre Lees-Melou were absent from the squad that faced Aston Villa in midweek for 'Covid-related' reasons, but while Christos Tzolis is the only confirmed player to test positive, more positive test results have been returned. The Canaries had discussions with the Premier League over Saturday's clash with West Ham and it was agreed to postpone as they have an insufficient number of players available.

Tottenham

Spurs were the first Premier League club to be hit by the Omicron variant last week and saw games against Brighton and Rennes postponed after cases reached double digits among players and staff. Those who tested positive for the virus are expected to return in the next couple of days after completing their 10-day self-isolation period. Spurs' clash with Leicester on Thursday was postponed despite initial demands to have the game called off were rejected, but Sunday's clash with Liverpool is due to go ahead.

Chelsea

After Brentford, the Blues became the latest club to be hit by a Covid outbreak, after it was confirmed ahead of their game with Everton that four more first-team players had tested positive. Mateo Kovacic was the first Chelsea player to get the virus in the outbreak this week, with Romelu Lukaku, Callum Hudson-Odoi, Timo Werner and Ben Chilwell following. Neverthless, their game with Everton went ahead and was drawn. Despite recording seven positive Covid cases, the Blues saw a request for their trip to Wolves rejected and Tuchel fumed at the decision to allow the game - which ended 0-0 - to go ahead on Sunday.

Liverpool

It was confirmed just an hour before kick-off against Newcastle on Thursday night that Fabinho, Curtis Jones and Virgil van Dijk were all out having tested positive for Covid. Midfielder Thiago also tested positive for Covid before Sunday's trip to Spurs and Jurgen Klopp said it is 'not possible' for the Reds to continue playing if more players fall ill.
