Tottenham failed to register a single shot on target as they suffered a 2-0 loss against Chelsea at Stamford Bridge on Wednesday night four days after being beaten 2-1 at Burnley.
The two successive losses mean Spurs now sit nine points behind leaders Liverpool and boss Mauricio Pochettino has already given up on the title.
“We made mistakes and lost the game, that is why we are disappointed,” he told BBC Match of the Day.
“Chelsea had one shot on target and one goal and we didn’t shoot – it’s difficult that way to win and we weren’t solid enough. In the small details the result was decided for Chelsea.
“The competition will put us in our place. It’s a 10-month competition, not just three or four months. We are disappointed now.
“After Burnley I said it was difficult, and tonight makes it impossible to fight Man City and Liverpool.
“Only they can win the league – we must fight to win games and to be fair.”
