Such is Harry Kane's extraordinary goalscoring prowess, the fact he has gone two league games without a goal can be legitimately considered as a drought. In their midweek defeat to West Ham, Kane uncharacteristically missed a couple of good chances.
Mauricio Pochettino has put this down to the fact his striker is currently being forced to wear a face mask to protect his nose, which he broke playing against Crystal Palace. The wearing of the mask is affecting Kane's peripheral vision, according to his manager:
He's playing with his mask and sometimes it can disturb you.
Maybe it's easier for Namanja Matic or different players that play behind, because creativity is not their problem. But you need to be sharp when you are offensive and creative.
Against West Ham, Harry had two or three clear chances to score. He was unlucky. It happens. I have full confidence in him. Sometimes there is a period in which it is difficult to score. He is not a machine.
It is an interesting theory by Pochettino. On the night prior to Spurs/West Ham, however, a mask-wearing Diego Costa plundered the winner for Chelsea against Norwich. That said, perhaps Costa's lack of peripheral vision helps him, as with a full panorama, Costa has a much higher chance of finding a defender with which to fight instead of concentrating on scoring goals.
