Nigel Worthington is still hoping to add to his backroom staff for the final four games of his contract with the Irish FA.
The Northern Ireland manager has appointed two men, in his own assistant manager and goalkeeping coach.
They worked with the squad in the build-up to last month's game against Liechtenstein and although Worthington wanted to add further staff before Saturday's trip to Latvia, he is still looking to so that.
"I thought it was only fair and right that I had my right-hand people along with several of the staff who were already on-board with the IFA and I have my two right-hand men in Glynn Snodin and Fred Barber," he said.
"I will be looking to address the sports science side of things and add to the staff as we go along as that will help us.
"You never stop learning and I am very open minded, receptive to new information and new knowledge.
"We know that results are in many ways number one, but there are many things below that, for example, the sports science side, the fitness side and the preparation side, which is most important from a players point of view."
