Former Manchester United midfielder Kleberson has urged the club to move for Jadon Sancho and Saul Niguez.
The January transfer window is quickly approaching and Ole Gunnar Solskjaer is expected to reinforce his United squad, with attack and midfield being two areas to look to improve.
United have been linked with countless names already, with Erling Haaland and James Maddison of interest.
Borussia Dortmund star Sancho is another player who has caught the eye of United. The 19-year-old has continued his blistering form this season after scoring in seven consecutive games and becoming the first player in Europe to get into double figures in goals and assists.
Kleberson believes the exciting winger would make a massive impact at Old Trafford.
"It’s a lot of money to be spoken about but he would make a big impact and add a lot to the team," the Brazilian told Bet New Jersey.
"He really is a great player and very exciting. A lot of players are wanting to come to Man United now as they come to play attacking football and make a good impact on the team, imagine if you had him, [Mason] Greenwood, [Daniel] James and [Marcus] Rashford all playing together.
"Solskjaer is so good for this team and working with the young players so I hope that he gets given the opportunity to continue."
Atletico Madrid's Saul has been linked with a move to Manchester several times in the past and Kleberson believes the all-action midfielder is a perfect fit for United.
"I like the speculation around Saul, he’s a great player and at 25-years-old he’s the right age to come into Man United, a big team, big club and play really well," he added.
"He’s a very talented and dynamic player, a bit different to what we have in the Premier League.
"More stylish and technical with his passing and movement, he understands how to play fast and turn defence into attack. As a box-to-box midfielder, he can fill that role well for Man United bringing a level of consistency which is what they really need.
"He can probably help more on the right side because if you saw Man United play, most of their opportunities come from the left."
