Tevez has embarked on a short holiday while the wrangle over his proposed big-money move to Old Trafford is sorted out.
With FIFA due to settle the matter of Tevez's registration at some point over the next month, the Argentina striker is going to require a bit of patience before his career takes off again.
Yet Tevez is unlikely to endure the length of frustration Hargreaves had to suffer before sealing his own transfer to United.
With Bayern Munich playing hard ball, it was almost 12 months from Sir Alex Ferguson making his initial approach that the 26-year-old finally completed his £18million Premier League switch.
"Every player would love the opportunity to come and play for Manchester United and I am sure Carlos is exactly the same," said Hargreaves.
"Sometimes, these things are difficult. We are all aware Carlos Tevez is a fantastic player who is obviously wanted by the club but it is tough to say what the situation is at the moment.
"However, once it is sorted out, I am sure he will be eager to come here. Once Manchester United are interested in you, it is very difficult to say no."
While Hargreaves hopes he is ultimately able to greet Tevez as a fellow summer arrival, his main priority is to get back on the field again.
A knee injury which flared up at the beginning of pre-season training prevented him from featuring in Tuesday's draw with Urawa Red Diamonds and Sir Alex Ferguson has already ruled the Calgary-born player out of Friday's encounter with FC Seoul.
Indeed, the United boss has cast doubt on Hargreaves' chances of playing any part in the four-match Far East tour at all, claiming he needed to make 'an assessment' of the midfielder's fitness before determining whether he should be risked.
Hargreaves is more hopeful, even if he realises the priority is to ensure he is ready for action when the champions begin the defence of their crown against Reading on August 12.
"The plan is certainly to be fit for the first game," he said.
"But then again, the plan was to be fit for all the games on tour.
"I have missed one and I will probably miss tomorrow but hopefully I will be fit for the last two.
"My knee just flared up a little bit after the first intense training session. At the moment I am just trying to be careful with it."
While Hargreaves was restricted to running, Nani played a full part in an extensive training session at the rain-lashed Seoul World Cup Stadium and is expected to play some part.
With all 60,000 tickets selling within six hours, United's popularity in South Korea is obvious, even though Park Ji-sung will not be involved due to his own long-term knee injury.
