You say six but I think it's 8 -
Lenglet handball - no pen
Mitoma goal - disallowed
March last man foul - no red (not even a free kick)
Wellbeck goal - disallowed
Foul on Mitoma - no pen
Lenglet double-handed shirt pull - no pen
Perisic two-footed lunge - no red
Foul on March - no pen
All...
That was (another) atrocious decision.
I am as reluctant as anyone to believe in match rigging, but the number of critical decisions that all went in Spurs favour was utterly ridiculous.
