Only the injured Paul Pogba is unavailable to the intervening time manager for the Red Devils first game in 16 days.
United's games in opposition to Brentford and Brighton have been the various 12 Premier League games to be known as off over the past weeks because of a wave of coronavirus infections as Britain battles record case numbers.
"The last education session we had eight outfield players and 3 goalkeepers after which we closed down the education ground in order to break the chain," said Rangnick on Thursday.
"Today changed into the 0.33 day of training this week and we had 25 outfield players. Paul Pogba continues to be the only one missing out, everybody (else) changed into on board."
Rangnick added that the vast majority of those to have Covid had very little signs, which allowed them to remain in form at the same time as education from domestic.
"The development of the final week became extremely superb. As a ways as I may want to see in training they're all in excellent form," he added.
"They did their homework. They all have their agenda to teach at home.
"They stick with that time table and programme and from what I saw in schooling maximum of them - if no longer they all - might be to be had."
The fixture congestion due to a series of postponements has once more raised issues over participant welfare.
Rangnick sponsored the calls of Liverpool boss Jurgen Klopp and Manchester City manager Pep Guardiola for the reintroduction of 5 substitutions to ease the weight.
