Only three Premier League clubs will be able to spend money on transfers this summer, an agent has told former Liverpool and Tottenham director of football Damien Comolli.
Comolli, who was in charge of transfers in his role at both clubs, believes this "window will be very different" due to the financial impact of the coronavirus.
But, as only a few clubs in world football can match the financial might of United, Comolli has told Sky Sports News he thinks "there will be very little cash available" for transfers this summer.
"An agent was telling me the other day, that there are actually only three clubs in the Premier League will be able to spend money next summer in the transfer window," Comolli said.
"I don't know if this is correct but usually when agents tell you things like this, they usually get intel.
"We might see very little transfer activity, we might see swaps, we might see loans and I think we are going to see a massive decrease in transfer fees and transfer activity, at least transfers involving money.
"The longer this crisis goes on, more clubs are going to be in a financially difficult situation. The first thing that will be impacted will be player remuneration, the second thing will be transfer fees."
When will fans be allowed in stadiums again?
Comolli is an advocate for the season to resume without fans because he believes the need for matches to be played behind closed doors could stretch until the end of the year.
The former Liverpool and Spurs director of football says the resumption of the season could offer fans a release during the coronavirus crisis, adding that football has a "duty to fans" and a "duty to entertain".
"There are millions of fans who cannot come into stadiums and will be happy to have something else - at night or during the day - to think about, away from the virus and all the issues they've got to think about," he added.
"I think having football on TV would be a positive, personally. I wouldn't be surprised if we can't play without any fans until the end of 2020 - not just the end of this season. People say we shouldn't be playing behind closed doors to finish this season, but what about next season."
'Tottenham might struggle to spend'
The impact of the coronavirus could also have profound implications for Tottenham and their ability to spend in the transfer market, according to Comolli.
While the Frenchman has predicted difficulties for the vast majority of Premier League clubs, the added burden of managing the cost of their £1billion Tottenham Stadium could present an additional headache for Daniel Levy.
Comolli believes Spurs will have to be cautious, likening their situation to that of fierce rivals Arsenal in the years following the opening of the Emirates.
He said: "If they are not doing well in the league, if the transfer market is difficult for them, if they are not qualifying for the Champions League, people should understand that they have to be very, very cautious.
"Remember the whole debate at the time where Arsenal had to pay for the Emirates, for the building of the stadium, and people were criticising why they don't spend money? They did not have money to spend.
"It was very simple and I think Tottenham are in a situation where they have some money to spend I am sure, or they will have had without the virus, but that virus will create a situation for them because they have got this huge debt.
"It's healthy debts because have built a stadium and have this incredible asset, but they still have to pay for it."
