The Terriers gaffer says the player is not yet where he wants him to be.
Despite his obvious talent winger Jamie Paterson was not in the plans of Dougie Freedman for the start of this campaign.
The 23-year-old had an up and down start to life with The Terriers with injury playing a big part but he is now in top form.
Paterson has scored three goals in his last five games and Brentford have been credited with an interest in the player.
“It’s very easy for me to say that because Jamie is here until the end of the season, there is no question about this,” said the boss.
“I like him as a player and a person, but like many of my squad. he is not yet where I want him to be.
“I think Jamie knows we can help him develop, and we will work carefully with him.
“If he progresses as we hope, (we) would be interested in keeping him and we will consider our next move in due course.”
So it seems that Paterson will not be heading anywhere this month, with his loan deal in Yorkshire seemingly concrete.
Whether or not he will take him on at the end of the season however seems to be in doubt.
Wagner is trying to get players into his pattern of play and the condition he requires at Huddersfield before deciding whether they have a future at the club and right now he seems to think that the Forest man is not at that point.
But if he continues to play like he has been recently, then they will surely look to sign him come the end of the season.
