He's definitely going to have to up the intensity some, especially if we play a the standard 4-2-3-1. But I think he can do it. He's actually a pretty quick dude when he's at full pelt.
What I think that we as Liverpool fans are going to have to realize here pretty quick is that goals are no longer going to come from the wings. Gone are the days where we have upwards of 60-70+ goal involvements from the wing. The goals and goal involvements are now going to come centrally, through a No. 9 in a more traditional sense. Thus our No. 9 will probably be hanging out up top in those attacking spots, and doing slightly less Darwin Nunez or Bobby Firmino. Not saying they aren't going to be required to run, but more so that we are not going to see them tracking back all over the field.
