The Tottenham boss is keen for the Belgium international to influence proceedings in the final third more and has backed him to improve his goalscoring figures
Dembele has featured in 32 of Tottenham's 34 matches this season and the Belgian midfielder has impressed Sherwood, who succeeded Andre Villas-Boas at White Hart Lane last month.
The 26-year-old has scored just four goals in 74 appearances for Spurs, but Sherwood has backed him to improve on that figure and is encouraging him to have a greater influence in attacking areas.
"Mousa's a nightmare to play against because he can drop his shoulder and leave you on your backside," the Spurs boss told the club's official website.
"Opponents can't get the better of him physically either. He's such a strong man; he gets away from players; he's a real top talent.
"We're trying to get him further forward to play in and around the penalty area because he has the capability of creating and perhaps scoring more goals. We're getting him into the areas to achieve that."
Dembele joined Tottenham from Fulham in August 2012, having previously impressed for Willem II and AZ in the Eredivisie.
