Boateng, 34, refused to commit to Hull's Championship campaign next season, indicating instead that he would like to stay in the Premier League if the chance is afforded to him.
Boateng and his Hull team-mates watched as Steve Gohouri's acrobatic injury-time goal earned Wigan a 2-2 draw at the DW Stadium, which confirmed Hull's drop out of English football's top flight after two seasons. Hull were all but down before the match, needing maximum points and a goal difference turnaround of 20 to threaten West Ham's survival.
Boateng admitted: "It's been coming since Sunderland last weekend, but we tried to take it to the last game of the season today and what makes it disappointing is conceding in injury-time again - the equaliser is so hard to take. Everyone at the club has made mistakes, including myself - but on a personal level I think we've enjoyed our time under Iain Dowie.
"When he came in he bought calmness to the place, everybody felt we could have some belief we could maybe make it (survive), but it's just unfortunate we have not collected enough points again. The players are happy with the (coaching) staff currently - but it's up to the chairman and the board.''
As for his own future, former Dutch international midfielder Boateng added on Sky Sports News: "I would love to stay in the Premier League. I've enjoyed my time in England and the Premier League has given me a wonderful life. It's great to be a part of it and hopefully it'll continue for another season or two.''
