Pictures appeared on social media on Tuesday of Mourinho holding a makeshift training session for midfielder Tanguy Ndombele, while Davinson Sanchez and Ryan Sessegnon were seen running together, breaching the two-meter distancing rule.
“It is vital we all play our part and follow government advice in order to support our heroes in the NHS and save lives.”
Tottenham has since reminded players of their responsibility during the lockdown period.
“All of our players have been reminded to respect social distancing when exercising outdoors. We shall continue to reinforce this message,” read a statement from the English Premier League club.
The UK government has urged people to stay at home and to only leave the house if necessary.
People are permitted to exercise in local parks once a day, but only with a member of their own household.
London Mayor Sadiq Khan was critical of the club for appearing to flout government guidelines and called for both players and staff to act as role models.
“My concern is people, particularly children, who may support Spurs or may follow football, may watch these images, pick up a paper or watch the internet, and think if it’s okay for them, why isn’t it okay for me?” he told the television show “BBC Breakfast” on Wednesday.
“I don’t think it is necessary to be training in close proximity with another player who may be carrying the virus.
“What you’re doing is inadvertently, unintentionally, potentially spreading the virus. You shouldn’t be doing that.”
Tottenham has also recently been criticized for their decision to furlough some non-playing staff during the coronavirus pandemic.
Those employees affected will receive 80% of their salary through a financial rescue scheme introduced by the government.
The club’s chairman Daniel Levy is now being urged to reverse his decision, as Liverpool has already done.
