Johnson has endured a stop-start season so far, and he has only made six appearances in the Premier League to date.
However, the winger was in fine form in Sunderland's 3-0 win over Newcastle United at the weekend, and Allardyce has challenged him to play at that level on a consistent basis from now on.
“Adam Johnson is a match-winner for us,” the 61-year-old manager said. “He’s got that much ability and we want him to shine and express himself that way on a regular basis.
“I’d say that about everyone who has Premier League experience here. If you lose your place, where has your form gone? Why are you not using that experience to your advantage?"
Johnson has the ability to be one of Sunderland's most productive attacking weapons, and it seems that he could be given a key role under Allardyce.
The 28-year-old's dribbling skill and creativity means that he can unlock defences, and that will be crucial as the Wearsiders look to improve their cutting edge.
Sunderland have struggled for goals throughout the campaign so far, but they were ruthless in their match against Newcastle.
That win has boosted spirits at the Stadium of Light, and the North East side could move out of the relegation zone if they are able to beat Everton on Sunday.
