Uwe Rosler was 'amazed' by his Wigan players' confident performance against Sheffield Wednesday.
The former Brentford boss replaced Owen Coyle at the Latics' helm at the start of December and told FL72 Preview he has been hugely encouraged by the attitude and quality in the Wigan squad.
With last season's Premier League outfit languishing in mid-table following a disappointing start to life back in the second tier, Rosler steered his new side to victory over Bolton in his first Championship game in charge, before their rain-hit contest with Wednesday was abandoned in the second half, with Wigan leading 1-0 at Hillsborough.
"The conditions at the beginning were perfect and we used those conditions very well," said Rosler.
"I was amazed with the confidence my players approached the game with. We dominated the first half and we should have been safe by half-time.
"But I had some fears by the end of the first half; already the rain had increased and in the second half I had no complaints about the decision from the referee."
Rosler revealed he has had little time to work with his new squad on the training pitch but has encouraged his players to stand by their passing game.
The German, who had plenty of praise for the experience and ability in the Wigan ranks, also explained he will be rotating his first XI over a busy and challenging Christmas schedule, which includes contests against three of the league's top five.
"I felt the players were very open to me from the beginning; they wanted some guidance and I gave them a framework to work in, but I also encouraged them to go back to when they are at their best, which is passing from the back up to the front," said Rosler.
"Everything started very well with the [Europa League] Maribor game, where they impressed me very much, and that continued in periods against Bolton and in a very good first half against Sheffield Wednesday.
"I'm dealing with players who have played at the highest level, players of a very high understanding of football.
"I didn't have much time on the training ground to practice with them but we went through DVD sessions, short interval sessions on the pitch and how they put that into practice against Bolton.
"We won a lot of balls centrally in the opposition half against Sheffield Wednesday, too, and we looked very good on the counter.
"I'm interested in playing a high tempo game in the opposition half and I need a lot of energy and with the games coming thick and fast I told the squad I would utilise the squad.
"Every player starts on a white sheet and every player can impress me."
Rosler conceded he was frustrated by not being able to spend more time working with his squad on the training pitch but is hoping Wigan can record positive results against Reading this Saturday and then when they take on Birmingham, Burnley and Derby, before modifying their method in the New Year.
"[The Christmas fixtures] can't get tougher than that," he said.
"We've not had much time on the training ground; at the moment it's just playing, recovering, maintaining and playing.
"But the willing in the camp is very high, the quality is there and now everyone has a new lease of life, can impress and I believe we will come in a good way over this period.
"In January, February, when we have more time on the training ground, we will improve."
