In his match programme notes for yesterday's draw with Hull City, Benitez reflected on last week's win at Blackburn Rovers: "People regularly talk about the strength in depth and I think last weekend showed we have that.

"They are young players who can be part of this squad and can make a difference. If everyone does that we can achieve success."
