Manchester United midfielder Fred has admitted that he is unhappy with his lack of football since moving to the Premier League.
Fred joined United from Shakhtar Donetsk during the summer transfer window, with the midfielder costing the Red Devils more than £50m.
The 25-year-old has only played twice in the Premier League since the end of September, though, and was not involved in Saturday's 2-2 draw with Southampton.
Fred was also left out of the Brazil squad for last month's clashes with Uruguay and Cameroon, and the midfielder has conceded that his current situation is not ideal.
"I've played very little at United, so it's normal for [Brazil boss] Professor Tite not to be able to evaluate me, even though I've worked hard with him before," Fred told reporters.
"Of course, I was annoyed, but I have to know how to deal with the sadness to be able to help me take a step forward. The coach has chosen not to put me in the team. That's his choice. I still do my job and I can't let it affect my mindset, I cannot let that shake me. I have to be patient.
"It's been a bit of a difficult start for me at United because I have not been playing so much. I had a lot of games in Shakhtar, but it's a little bit different here. It's normal, of course, a process of adaptation to a different league.
"Although I've been to Europe before, now I am in a different country and I have to go through a new process of settling in. But today I see myself much better and I hope that my football will be 100% soon.
"I think I had a great performance against Young Boys in the Champions League. We had the opportunity to score a few times before we scored the goal at the end, but I was very happy to have returned to the field and I hope to continue playing more."
Fred has scored once in 10 appearances for United this season.
