The Bulgarian believes that signing a new frontman could affect the progress of young striker Mason Greenwood and he wants to see more of Anthony Martial in the centre-forward position.
“I don’t think United need to sign a striker in January as they have decent options up front already,” he told the Evening Standard.
“I want Marcus Rashford to get better and better, I’m a big admirer of Anthony Martial and am keen to see Mason Greenwood get more time on the pitch.
“I think United have the talent there and signing a new striker, whether it’s an emerging talent like Haaland or the more experienced Mario Mandzukic, could discourage their young players.
“I know there’s speculation about Haaland coming to United in January. He’s a big centre-forward, an old-fashioned target man who scores tap-ins — so quite different from Rashford and Martial.
“Haaland would offer United something different, but coming from Red Bull Salzburg in the Austrian Bundesliga would be a massive step up, so United need to think carefully about if he’s the right man and how he would fit in with their style of play.”
Berbatov added that United must buy strikers that suit Solskjaer’s style of play.
“If they could get Harry Kane then that would be great, because he has everything,” added Berbatov. “But it’s not going to happen.
“United fans want to see strikers who play with the element of surprise, beating defenders and shooting from different angles, so the way to deal with the pressure as a new United striker is to be different.
“There aren’t many strikers around who are available and would fit into United’s system.”
