"Dimitar does not want to play for another club in England," Danchev told the sports website goal.com.
"He would like to try a new challenge in another league. It has been a frustrating season and now he just wants to play football," he added.
The 31-year-old striker lost his prime spot on United's squad earlier this season, making just 12 appearances in the English Premier League, and manager Sir Alex Ferguson has now made him available for transfer, goal.com reported.
The website predicted a possible return to Germany, where Berbatov played for Bayer Leverkusen, with top clubs such as Bayern Munich and Borussia Dortmund reportedly expressing interest in the former Bulgarian international.
Berbatov joined the Reds from Tottenham Hotspur in 2008 for £30.75 million (38.3 million euros, $49.6 million) and was joint top scorer in the English Premier League last season alongside Manchester City's Carlos Tevez.
