Former Liverpool defender Dietmar Hamann believes it's time for Matsui Hummels to leave Borussia Dortmund and move to Manchester United.
The 26-year-old center-back has been linked with a move to England throughout this season, and Manchester United coach Louis van Gaal has also shown interest in the German.
Earlier, Hummels admitted that he will consider his future at the end of the season, but he did not confirm any talks about a move to Manchester United.
"He is attracting interest from many clubs. Hummels has played many great games in Dortmund, but the transfer seems beneficial for both teams," Hamann told Sky90.
"He has done as much as he could in Dortmund. Right now, he needs a new challenge. Van Gaal wants to see him in their ranks, and United need someone to solidify their defense."
