Analysis - what to expect
Widnes have shown signs in recent home games that they are raising their performance levels in front of their fans but they face a quality Hull side who are in excellent form. Lee Radford's men will be keen to keep the pressure on Castleford at the top and as long as they avoid complacency, everything points towards an away win.
