Grealish was one of the club’s best players under Tim Sherwood towards the end of last season, but he’s far from being the complete player, which is something he appears to have picked up on.
“Great credit to him because he works ever so hard in training. He's always one of the lads out every day,” he said.
“He's still working on parts of his game he can improve on.”
Sherwood will be looking at players like Grealish to put in the extra efforts for the Aston Villa cause, which help the team and have a positive impact for them personally.
Grealish has the potential to be a special player in his position over an extended period of time, but it’s important that he works hard to identify the key areas of his game where he can make strides and improve.
Arsenal deserve credit for the way they shut out all of Aston Villa’s key players in the FA Cup final last weekend and Grealish needs to study what went wrong in that game.
The challenge for any player who has excelled under Sherwood’s guidance is how they are going to reinvent themselves for next season.
Grealish is now a marked man and someone that opposition teams are going to be well aware of when they are preparing to play Aston Villa.
He’s got the touch, the speed and the intelligence to cope with different challenges and if he can work hard in training to add bulk and fitness, he’ll be a very difficult man for any team to get the better of.
