Partizan Belgrade midfielder Zoran Tosic has no regrets over his time with Manchester United.

The Serb faces his former club tonight in the Europa League.

He told the Daily Mail: "When I went to United they were champions of Europe and England. When you see United now, we have to be honest that the team is not as strong as it was.

"The Serbian league and Premier League are totally different worlds. When I was younger, I never went to the gym. I didn't know what the gym was. When I went to United, I saw that everyone went to the gym before or after training. Most players had a gym at home as well!

"In Serbia at that time, you came to training for an hour and a half, you finished and went home. But I saw Cristiano Ronaldo or Ryan Giggs, who was 36 at the time, come three hours before training and go to the gym. I wasn't ready to play for United in that moment."
