Dean Smith insists Aston Villa cannot continue to rely on Jack Grealish to win games.
Villa suffered a 2-0 home defeat at the hands of Tottenham on Sunday, with Grealish missing for the sixth straight game.
Speaking after the final whistle, Smith said: "With Jack you get those little bits of quality which can open up teams and would probably have opened up Tottenham.
"Unfortunately we haven't had him and at the moment the other players have not taken the opportunity.
"We were excellent at Leeds last month with a superb defensive performance but we didn't create many chances.
"Players have to play themselves into form. We have a number of players who have shown really good form over the first half of the season and it is not there at the moment.
"We have to help them as coaching staff but they have to regain their form."
