Borussia Dortmund's apparent openness to selling Jadon Sancho this summer means Manchester United have not ruled out a move for the winger.
United made Sancho their top priority in last summer's transfer window but Dortmund were unwilling to negotiate, placing a £120million price tag on the England international.
After spending £46m on right-wingers Amad and Facundo Pellistri, the Reds are prioritising moves for a centre-forward and centre-back this summer.
Sancho's form has dipped in the Bundesliga this season, yet the MEN understands that United have not fully ended their interest in the 21-year-old.
In Sancho and Erling Haaland, Dortmund have two of the highest-rated young players in the world on their books, and the German club appear to have taken the same non-negotiable stance with Haaland this year that they had with Sancho last summer.
Yet, speaking to DAZN, Watzke admitted the situation with Sancho this summer is slightly different to Haaland's and says an exceptional offer will see the club consider their options over the winger's future.
"I'm not getting involved in probabilities, it's no good," said Watzke when asked about the prospect of both Haaland and Sancho being at Westfalenstadion next season.
"Jadon Sancho has been with us much longer than Erling Haaland. We'll have to speak to Jadon too.
"If there is an exceptional offer we will discuss it with the player and the agent, as always.
"Nonetheless, I am very sure that the transfer market will only run to a very limited extent this summer.
"Especially at the really big clubs you can see what kind of wounds coronavirus has inflicted, and they are not small ones that heal within two weeks."
Dortmund are currently fifth in the Bundesliga table, seven points adrift of the final Champions League qualifying place with six games to go this season.
It could well leave Dortmund facing a financial blow should they fail to qualify for Europe's premier club competition.
While they are a well-managed club at boardroom level, Dortmund have been hit hard by the lack of fans at games this season, having previously enjoyed the highest average attendance in European football.
It left Watzke to admit earlier this year that "if there are going to be no spectators in stadiums next season then we have to start thinking about selling players".
Last summer saw Dortmund set a date that United would have to agree a deal to sign Sancho by as BVB made their plans for the season ahead.
Yet, speaking last week, Dortmund sporting director Michael Zorc played down the prospect of similar happening this season with the key duo.
"I don't see the need to set deadlines at the moment," he said.
The club's current situation could well mean that United find a Dortmund hierarchy more receptive to selling Sancho this summer, should they opt to renew their interest in the winger.
