Zoran Tosic has accused Sir Alex Ferguson of not giving him a chance at Manchester United.
Serbia international winger Tosic sealed his departure from Old Trafford earlier this week by joining CSKA Moscow after just 18 months at United.
Tosic made only five substitute appearances in the Premier League for the Red Devils and spent the second half of last season on loan at German side Cologne.
The 23-year-old feels he had no choice but to leave Old Trafford after growing increasingly frustrated with his lack of first-team opportunities.
"I'm already 23, but Manchester United didn't give me a chance to prove myself," said Tosic.
"Obviously, I'm an athlete, I have ambition, but I want to show myself on the pitch, not on the bench. That's the main reason I left.
"They could have considered loaning me, but Manchester United wanted to sell and sell they did.
"CSKA Moscow, in my opinion, are quite a famous club, consistently playing in European competition and fighting for the Russian League title."
