Wolves had the lead through Santi Bueno before Joao Palhinha struck for Spurs in the 90th minute.
Pereira said afterwards: “Congratulations to my team, to my players, we deserved the three points, but football is football.
“Football sometimes is not fair and in the last minute we conceded the goal. But keeping this spirit, playing in the way that we play in the second half, we will get our points.
“We were the best team in the second half. In my opinion, we deserved to win, but that is football. I need to keep my balance because it is very difficult to concede a goal in the last minute, but football is what it is.”
The Portuguese also said: “The last game against Everton and today, I think now, mentally and tactically, we are in conditions to compete.
“But it’s difficult. I said to them, we must keep this spirit, this mentality, we must keep playing like this in this way, and we'll get points for sure in the future.”
