The club's executive vice-chairman has come in for a lot of fire over their messy transfer business this summer.
"United need a real striker, a proper No.9, one like Erling Haaland," Meulensteen wrote in his column forManchester United Supporters Club Scandinavia.
"Just look at Bayern Munich about how important a striker is for them. Ask Tottenham or Leicester what a striker means. For me it is strange that a striker has not been the main goal for United.
"Cavani has an impressive scoring record but he knows nothing about Premier League. I really hope he adapts fast and gets started.
"It's hard to understand how United end up in the position that they have to hurry around for players on deadline day."
Meulensteen also believes Woodward was wrong to pursue a player like Sancho.
He added: "Every day in the transfer window there were rumours about Jadon Sancho. Now the transfer did not happen anyway but my opinion is that Sancho is not what United first and foremost need. Spending so much money on such a player raises many questions.
"And one of them is what role should Mason Greenwood have played?
"Another thing with this transfer saga is that if Dortmund had been ready to sell him, then they would have sold him earlier in the summer so they had time to sign a replacement.
"As time went by before the deadline, it seemed unlikely to me that it would happen.
"Dortmund have been very steadfast all the way, but my honest opinion is that Sancho is not worth £100 million."
