Former Premier League winner Alan Shearer highlighted the weaknesses that Leicester City faced in the Tottenham Hotspur system this season.
Mauricio Pochettino has won his team in the last 12 league games with 30 points, more than any other player in the English league, including title rivals Liverpool and Manchester City.
With 26 games played, they are five points behind the leaders and reigning champions while the game is over.
A number of experts and managers have chosen Spurs as their real competitors this season, including Jamie Carragher and Pep Guardiola.
However, Shearer has warned Tottenham that Leicester's teams have shown how they can defend themselves in the 3-1 victory against the Foxes at Wembely Stadium.
The team of Claude Puel was the better team for most of the match and could have won the match if they had not fulfilled their chances.
Spurs have yet to leave to play Chelsea, Liverpool and Manchester City before the end of the season as they seek their first trophy under Pochettino. Shearer has told the Argentine where to focus on fine-tuning his tactics in the coming weeks.
"I think Leicester has identified and identified the full-back positions as weaknesses for Tottenham and areas they could exploit," he said in the BBC Sports program "Sunday of the Match of the Day 2".
"They knew [Kieran] Trippier and [Danny] Rose would play high, Tottenham would go wide, and Trippier did not get inside.
"Poor positioning. Fast ball through the back position. Should be better."
The former England international, who won the Premeir League trophy with Blackburn Rovers, picked out a few passages as he analyzed what went wrong with the Spurs.
"See how tall Tottenham's full-backs are," he said. "The room they leave behind.
"[Jan] Vertonghen fouls [James] Maddison for the Leicester penalty, but it's because of the place Leicester players have to wait.
"It all comes down to the fact that Spurs wants to be positive and wants to bring men forward, and Leicester will have looked at that and thought they could cause problems there."
Jamie Vardy came off the bench to convert the penalty but was unable to convert the free-kick, although he later found the consulter's goal in the second half.
