Jones says Man Utd must not underestimate Hull
Steve Bruce's Hull side have lost just once at home this season and have conceded only three goals in East Yorkshire.
"Steve Bruce has done a great job there," Jones told MUTV. "He's got the team he wanted, the players he wanted and that's the reason why they are performing in big games. We've definitely got to be wary of them because they will be tricky opponents on Boxing Day."
The challenge with Norwich, who have lost only twice at home this term, may be in the quick turnaround in fixtures. "You can prepare for Hull but there's only so much time and so much preparation you can do," adds Jones.
"Against Norwich, most of the preparation will be on the tactics board and in the team meetings, it probably won't be much outside on the training pitch. But we've got to be ready for [the game]."
