Lingard has only played 867 minutes in the league for United this season as his last goal came against Cardiff 13 months ago.
"Jesse has a lot of energy and runs about a lot, but where he struggles is that he doesn't link up the play well enough and struggles with that final product," Saha told Bonus Code Bets.
"When I watch him play, I get really frustrated as he does a lot of things well, but his play in the final third isn't good enough, which is concerning for an attacking midfielder.
"He has a lot of talent and is a good player but struggles to get himself in the game sometimes and is unable to get himself in the right areas.
"When Jesse gets into the right positions, things will start clicking for him and he will get goals."
