A survey released by YouGov on Tuesday showed that 67% of Premier League fans believe VAR has made football less enjoyable, while supporters are also in favour of the referee using the pitchside monitors.
Spurs were trailing 2-1 to Southampton in their fourth-round replay but Lucas Moura equalised with 12 minutes remaining, before Heung-min Son's penalty with two minutes left sent Mourinho's men through to play Norwich next month with a 3-2 win.
Eric Dier and Tanguy Ndombele are given a recalls in midfield after being named on the bench for Tottenham's 2-0 win over Manchester City at the weekend.
"I think [Kane can play in] these two matches", Mourinho added.
"We started with a back five, resist, kept ourselves in the result and the only thing that wasn't in the programme was to concede a second goal, a second goal could kill us mentally".
"We are going to try and do everything to catch the teams above us, so it is going to demand a lot of consistency".
"But my team were the ones with more heart and went to their limit". The boys are fantastic and I'm so happy for them.
"I was immediately very upset that Sterling didn't get the red card and then that situation happened again and in one minute I was laughing and the next minute fuming", said Mourinho. No bishops, no kings, no queens.
The Spurs were able to preserve the tie heading into halftime despite a very unconvincing performance, while the Saints' strong showing was marred by an apparently serious knee injury suffered by midfielder James Ward-Prowse.
"I can not speak about the progress I want to make because I don't have the players I want and the team needs players to progress collectively, tactically and dynamically". Maybe we need them for something and he can help us.
"In the Premier League, we are not in a comfortable situation".
"I think the fact that now it is allowed to have the screen in front of us is not good for our emotions", Mourinho told a news conference ahead of Wednesday's FA Cup fourth-round replay against Southampton.
"It's hard to sub players during the game", said Mourinho. If you look at it in a pragmatic way, forgetting that they had their best players, they had their full team, they had one more day to rest, we were really in trouble.
