An ageing defender seemingly past his prime against a striker entering his athletic peak in the best form of his career.
Put that way, it doesn't seem wise for Jamie Carragher to face Wayne Rooney on Saturday, but that's what will most likely be the case, considering Carragher's vast experience in this match, and the fact that Rooney will be told by manager Sir Alex Ferguson to ditch the marking from Daniel Agger and channel his attacks in Carragher's position.
And, looking at the stats, it seems Rooney will get the better of Carragher.
The striker has scored nine goals this season, at a rate of one goal for every 4 shots on goal, having hit, on average, 6.2 shots per game.
Carragher has only blocked 3 shots this term at a rate of 0.4 per match, and, given the assist-making powers of Rooney's teammates, it seems almost certain Rooney will beat Carragher and get a goal in this match.
Rooney most likely won't get an assist, as he's only got two assists despite making 18 key passes, at a rate of 3 chances created per game and one assist in every nine key passes.
And, considering he's in a central position (which means Carragher's tackling can deny him), Carragher's 1.4 tackles won per game mean he probably will create at least one chance, possibly two, but won't necessarily claim an assist.
Either way though, Rooney has got a goal in him for this match, and wins the match-up against the Liverpool veteran.
