The Republic of Ireland international notched the winner for his country on Saturday after playing up front for Brian Kerr's side.
The former Luton Town man has played in the heart of defence and attack for both club and country as he shows his versatility.
The 23-year-old Doherty is wary that playing in both positions is a tough task and knows that he must stick with one if he is to continue to improve.
He now says that he will sit down in the summer and make a decision about where he prefers playing and concentrate on making a name for himself either banging the goals in or trying to prevent them at the other end.
"I get asked all the time whether I prefer playing as a centre back or centre forward and it is something that I'm not really bothered about," said Doherty.
"But it is something I've got to look at, probably this summer.
"I've got to sit down and really think where I want to play because it's too hard now to try and do the two positions, at least at the highest level, so I've got to talk to the coaching staff and try to find my best position.
"It is a massive decision for me and something I'm going to have to talk to a lot of people about because you do find it hard to train and play in one position and then maybe change a week later, and I am finding it quite hard, especially at Tottenham.
"I think I've been playing okay, but the performances haven't been what I want really. I quite enjoy playing in different positions but if you want to play at the highest level in The Premiership you have got to try and perfect one position and that is really what I'm looking to do now.
"It is a bit of a worry to keep chopping and changing all the time and it is something I've got to really look at."
