NEIL Harris admits Magaye Gueye is not "happy" with his role as a super sub but says the Frenchman is understanding of the situation.
Gueye has scored in two of his last three appearances for the Lions – taking his tally for the season to five – but he hasn't started a game since early February.
The 24-year-old would like to be a regular in the side but Harris believes the attacker is a great "impact" player to bring off the bench late in games.
"You need subs like that in the modern game, definitely," Harris said, speaking after Gueye's match-clinching strike against Wigan on Tuesday.
"A lot of football all over the world is about staying in the game and then unleashing subs to make a difference. Magaye has certainly got that ability.
"The lad's got some terrific talent and it's just getting the best out of him when possible.
"Is he happy? I don't expect any of my players to be happy if they're a sub – unless they're promoted to the bench from being out of the squad.
"So no, he's not happy but he understands. He wants to play, to win and to score goals.
"If he comes off the bench and scores in each of the the next four games, I'll be delighted."
