Huddersfield manager Lee Clark challenged match-winner Joey Gudjonsson to maintain the form he showed in his side's 1-0 win at Charlton for the rest of the season.
Gudjonsson boosted Town's automatic-promotion hopes by scoring a late free-kick to keep Clark's side level on points with second-placed Southampton.
Clark said: "Joey Gudjonsson is a class act. Joey frustrates me because I know how good he is and over the course of the season consistency has been the key with Joey."
He added: "But when he plays in that type of form, and no disrespect to the lads, but at this level he is too good.
"That's why I pursued him in the summer. To think we got him on a Bosman from Burnley is a good bit of business.
"My challenge personally to Joey is for him to play as well like that as often as possible."
Charlton manager Chris Powell had no complaints with referee Oliver Langford's part in Huddersfield's winner.
The game appeared to be heading for a goalless draw until Huddersfield were awarded a free-kick 30 yards from goal with seven minutes remaining.
Gudjonsson's initial free-kick was handled by Kyel Reid, prompting Langford to move it forward 10 yards and this time the Iceland international drilled a stunning shot past the wall and into the net.
Powell said: "I suppose it is indicative of our luck and where they are at that we have more chances, we don't take them and seven or eight minutes from the end they get a re-taken free-kick."
