Liverpool manager Jurgen Klopp says he is "really happy to be back" to watch his "wonderful football team again" as they continue preparations for the Premier League's return on 17 June.
Klopp's side are 25 points clear at the top of the table and chasing the club's first league title for 30 years.
Players returned to contact training on 28 May but they will continue to be tested twice a week for coronavirus.
"I have missed it so much it's unbelievable," Klopp told BBC Sport.
"I know it's not the most important thing in life but it is my passion. I hope the people are looking forward to it because we are."
