Non-essential shops will be closed from Tuesday after cases in the city accounted for 10 per cent of all nationwide positive tests over the past week.

A Leicester spokesman said: "All parties remain entirely satisfied that, through the continued implementation of our Covid operations plan, the club's football operations can continue to safely function under existing protocols and, in doing so, there will be no greater risk posed to club personnel, visiting teams or our surrounding communities.

"Consequently, first team training will continue at Belvoir Drive and our forthcoming Premier League fixtures remain unaffected."

Premier League chief executive Richard Masters said the incident highlighted the fragility of the competition's Project Restart plans, but contingencies were in place for such an occurrence.

Masters also said there was a risk of the season not being completed if there were multiple lockdowns like this, and he added: "It is all dependent on the course of the virus. We have shown our flexibility to that, but we have to operate within government guidelines."

Leicester take on Everton at Goodison Park on Wednesday night, with concerns surrounding the form of striker Jamie Vardy.

The former England forward has scored only twice in his last 10 matches for the club stretching back to Boxing Day, but Leicester boss Brendan Rodgers says others must take responsibility for goalscoring as well.

"There is a lot of spotlight on Jamie but it is not just about the striker, it is the team's contribution. That is something we need to improve," Rodgers said.

"This is the responsibility of the team and it's my responsibility to find ways we can get back to increasing our goalscoring. It's the responsibility of everyone.

"I think we would want to give him more service but we are looking at ways to develop and get our wingers back to being involved, creating goals and scoring goals – and of course our midfield players."

Leicester remain third in the table but now have just a one-point advantage over Chelsea after frustrating draws against Watford and Brighton since the restart.

The 2016 Premier League champions have a doubt over James Maddison, who missed the Chelsea loss in the FA Cup last weekend with a hip injury.
