Speaking to Sky Sports after the game, Slot said: “I think it's obvious and clear that the wrong decision has been made, at least in my opinion. Because he [Robertson] didn't interfere at all with what the goalkeeper could do.
“Immediately after the game someone showed me the goal that the same referee allowed City against Wolves last season [John Stones’ last minute winner]. So, it took the linesman 13 seconds to raise his flag to say it's offside. So, there was clearly communication.
“That could have influenced the game in a positive way for us because in the first half we were so poor.
“We would have been lucky going 1-0 down at half-time, let alone if it was 1-1 or 2-1 down. So it has been an influential decision, which is not to say that we then would have had a result over here because you cannot predict how the second half would have gone.”
