Mauricio Pochettino has admitted that Tottenham Hotspur's performance against West Bromwich Albion on Saturday "wasn't good" as the Baggies ran out 1-0 winners at The Hawthorns.
Jake Livermore dramatically netted in the 92nd minute of the encounter to deal a blow to Spurs' Premier League top-four hopes.
Tottenham remain five points clear of fifth-placed Chelsea in the table despite the loss but the Blues have a game in hand on the North Londoners.
"In football you can dominate but you need to be clinical in front of goal and today wasn't good," Pochettino told BBC Sport.
"I am very disappointed because we lost the game. Still, we have it in our hands to be in the top four.
"We knew how they would play. If you want to be in the top four and challenge for the big things, you need to score in these games.
"It is in our hands. If we are not able to win the next two games we do not deserve to qualify for the Champions League."
Spurs will finish the season with games against Newcastle United and Leicester City.
