The former Sunderland and Wigan boss was officially announced as the Yorkshire club's new manager at a press conference on Friday afternoon following the departure of Nick Barmby
The former Wigan boss has been without a job since his sacking as manager of Sunderland last November and was reported to be reluctant to take the reins at the KC Stadium amid fears of available transfer funds.
But the 51-year-old opted to succeed Nick Barmby as manager, after the latter was removed from his post due to comments made in the media.
Former Hull City midfielder Bryan Hughes told BBC Radio Humberside: "I think it's a fantastic appointment, I really do.
"He's shown what his capabilities are as a manager and he's done it at the top level as well as getting promotion from this division.
"When I played under him he just gave everyone a belief that they could do well and he's great to work with.
"I think Hull have done really well to get him. It's a real coup."
