A 3-0 home defeat to champions Leicester on Saturday confirmed Alex's relegation.
Ultimately, a run of 10 games without a win means they will play basement football for the first time in 15 years.
"I am bitterly disappointed to get relegated, but I knew it was going to be tough at the beginning of January," he admitted.
"I have seen the fans have the desire and passion and that needs to come into the team and the whole club.
"I am looking for promotion next year."
