Tottenham boss Mauricio Pochettino admits the top four race is wide open.
Spurs meet QPR this weekend.
"It's not easy because seven or eight teams are fighting for that. We need to go step by step. We're in a good process. My worry now is to improve," he said.
"We have 11 games to finish the season. It's important to be solid.
"We expect a tough game. They're a strong team. It's a London derby and the three points are important. The squad is fully fit. We need to be ready because it's a difficult game. "We want to finish the season strong. We have time to work hard now and to be consistent."
