Eric Dier acknowledged Tottenham's hopes of Premier League glory are all but over after they went down 1-0 at West Ham.
Manuel Lanzini's second-half strike ended Spurs' nine-match winning run and means leaders Chelsea will go seven points clear with three games remaining if they beat Middlesbrough on Monday.
"It was already going to be hard before, so now it's even harder. That's all I can say really," he said.
"It's disappointing really because we were on a fantastic run and we didn't think it was going to stop.
"They made it hard for us, they played very deep and we couldn't create many chances."
Dier added: "We brought it [the deficit to Chelsea] back to four points but after today it's nearly impossible now.
"We'll give everything for these last three games, no matter what."
