Hugo Lloris admits Chelsea's FA Cup victory could give them renewed belief in the Premier League title race but insists Tottenham have not given up yet.
Spurs hoped to gain a psychological boost at Wembley by continuing the Blues' recent dip in form while extending their own excellent run of seven victories on the bounce.
Instead, however, Chelsea clinched a dramatic 4-2 win to book their place in the FA Cup final and reassert their status as the finest team in the country.
Tottenham are four points behind in the league but could be seven back by the time they visit an in-form Crystal Palace side on Wednesday. Chelsea host Southampton on Tuesday.
"We know that they have an advantage but we need to believe until the end," Lloris said.
"We knew before that this game can have maybe an impact for the rest of the season.
"But in football you need to believe because everything is possible and we don't know what will happen in the next few weeks.
"They are human and that's the case for us. The only thing that we can do is keep working hard, keep believing and playing the same way that we play in the last few weeks."
Tottenham have now lost a record seven consecutive FA Cup semi-finals and their latest disappointment also continued their struggles against elite clubs this season.
They have won only two out of eight league games against Chelsea, Manchester City, Manchester United, Liverpool and Arsenal, as well as losing to Liverpool and Chelsea in both domestic cup competitions.
Lloris believes Chelsea's superior experience may have made the difference on Saturday.
"I'm not sure but from the beginning we ran after the game, we ran after the score," Lloris said.
"We played in the way we wanted to play, that's the most important thing. That's why we have to keep our chins up. We made a good performance. And then it is about details.
"Chelsea, they are used to winning trophies. It's a winning team. And maybe they have more experience than us.
"But we try to make a good balance. In the way we play, we try to push but it was not enough."
