Spurs extended their impressive record at White Hart Lane this afternoon courtesy of an emphatic 4-0 victory over Watford, with Walter Mazzarri's men failing to provide any answers to the hosts' attack.
Mauricio Pochettino's side boast the best home record in the Premier League and have not lost a league game in front of their own fans since May 2016.
Spurs have scored 39 goals in 16 games on their own patch this term and Alli is adamant other teams will not be relishing a trip to N17 during the run-in.
"It was a fantastic performance by all the boys but I don't just mean the players on the pitch," he told Tottenham's official website.
"All the staff and the crowd today were fantastic - they really drove us on and gave us belief.
"People are going to be scared to come here. It's been unreal here. The fans are great and get behind us. They spur us on that extra bit."
Spurs still have to host Arsenal and Manchester United before the end of the season, with both fixtures set to play a major part in the battle for Champions League football.
But Pochettino's side, who are Chelsea's closest challengers, are still aspiring for more and remain determined to keep up the pressure on the Blues.
The Argentine coach said: "We must keep doing well. We must keep going. Our focus now is to win the next game. Our mentality is to keep pushing."
