The Oman international keeper had another excellent game at Stamford Bridge on Saturday, only being beaten after seemingly being impeded by Fernando Torres, which allowed Florent Malouda to score the winner.
Wigan must now pick themselves up for a huge game against Blackpool and Al Habsi hopes they can carry the positives from the trip to the capital into the game at Bloomfield Road.
"We concentrated and gave 100%, the whole team but in the end we lost the game. It's not easy to come here and play Chelsea," the on-loan keeper told Wigan Today.
"It's very disappointing because we came here and we showed ourselves and had some good chances but in the end we didn't score.
"We have to take the good things and move forward."
