Former Manchester United midfielder Kleberson is impressed by the improving form of Fred.
Fred has started United's last five matches, four of which have been wins.
“Fred has got a lot of expectation on him now, as he's shown his quality," Kleberson told the Manchester Evening News, via BonusCodeBets.co.uk.
"He's started moving the ball well and shuts down space for the opposition in midfield.
"When he first started playing alongside Andreas Pereira they struggled, but now they've got used to the tempo of the Premier League, they are starting to show their qualities.
"He can continue to improve but everything can change in football, so he needs to stay confident and keep his position in the side. As his position will come down to the team getting the right results."
