We lacked a bit of pace and Mané has added to that and brought real threat.
But it is pretty absurd to say that he is the only difference this year. Mané hasn't made Lallana, Firmino, Coutinho quicker has he?
The pace of play is much quicker and that pace is much more consistent this year. It isn't the pace of our players the opposition are struggling with, it is the pace of our play and how high we are pressing.
