Speaking to Alan Shearer for The Sun ahead of Saturday’s FA Cup final against Arsenal at London’s Wembley Stadium, Sherwood spoke highly of the 19-year-old attacker.
The former Tottenham Hotspur boss believes that Grealish can become a top player in the coming years, but he wants him to add goals to his game.
“He can be as good as he wants to be,” Sherwood said about the Republic of Ireland Under-21 international.
“He has still got a long way to go but he is a friend of the football. He receives the ball in tight areas and manoeuvres it.
“He always has awareness of his team-mates. If he can add goals to his game then we have a real player on our hands.”
Grealish is a genuinely talented young player who was superb for Villa in the final weeks of the recently concluded 2014-15 Premier League campaign.
The teenager failed to score a single goal in 17 league appearances, but he created 18 chances, and had a pass accuracy of 93% and a shot accuracy of 71%.
The 19-year-old won three headers, 23 dribbles and seven tackles in those 17 league matches.
Aston Villa finished 17th in the league table this season with 38 points from as many matches, just three points above the relegation zone.
