Beginning of april last year, without Kane, Son scored 3 goals in champions league (april 2019) So he didn't have drought in whole competition. And at that time, the team was more focused on CL, and Son was rested in some of those league game if i remember correctly. So he actually play well in that month.
And other month, Son played Asian game, so he missed many game.
So yes, you will have goal drought, if you miss many games.
You may note it says EPL games...?
Do you mean the asian games that took place in Aug/Sep 18?
He wasnt rested.... He got sent off against B'muff right at the end.
He's patchy.... It's OK to admit it.... So was Defoe.... Doesnt meant mean peeps don't love them.
BTW despite your desire not to play Kane at CF due to not scoring he's still had 2 goals and a number disallowed since restart.
